Article: If your thermostat is set to a high temperature, your gas bill is bound to be expensive. Try lowering your thermostat a few degrees to reduce your bill by 5-10%. For instance, turn the temperature from 70 °F (21 °C) to 68 °F (20 °C). Don’t keep the heat on in your home when it’s not necessary. Turn off the heat when you’re at work or gone on the weekends. The energy saved will reduce the cost of your gas bill. Some areas in your home need to be warmer than others. For example, it may be important to you to keep the main floor warm, while the basement can be a bit cooler. You can control the heat by installing radiator valves on every radiator in your home. These self-regulating valves allow you to control the temperature of each room by adjusting the amount of hot water goes to the radiator. Personal, or space, heaters use up a lot of energy. Plus, they are an inefficient way of warming up large areas. Avoid using them and instead look for more efficient ways to keep warm—like improving your home’s insulation. If you want to warm a small space only, a personal heater may be more effective than heating the whole home with a furnace. Choose a radiant heater, which are more energy-efficient than other models.
Question: What is a summary of what this article is about?
Lower the thermostat. Turn off the heat when you’re not home. Save energy with radiator valves. Reduce the use of personal heaters.

Problem: Article: If your jump rope is too long, you will need to adjust the length. There are a couple of different ways to adjust the length of your jump rope. The easiest way to adjust your jump rope’s size is by tying a knot or a couple of knots in the rope. Tie the knot as close to the handle as you can without letting the knot actually touch the handle. If you need more than one knot to adjust the size, tie one knot (or two) on each side of the rope. This method is best for beaded and cloth ropes. Make sure that you have enough space to jump rope and that you can see the topmost part of your jump rope as it swings over your head.  If you can jump rope in front of a large mirror, that is ideal. If not, ask a friend to watch you.  As you jump rope, notice the distance between the top of your head and the middle of your rope.  For beginner jumpers, this distance should be about 16-30 inches.   For fitness jumpers, this distance should be about 6-10 inches.   For speed jumpers, this distance should be about 2-6 inches. Speed and control If your jump rope seems too long or too short, you can always readjust it by adding or taking out one of the knots that you made.
Summary: Adjust the length of your rope. Test your rope size. Readjust your jump rope as needed.

INPUT ARTICLE: Article: You don't need to go out of your way to look ratty, but avoid obviously expensive clothing. Chances are you'll be negotiating over cheap items, and a fancy suit or dress tells the seller you can afford to pay full price. Don't forget to remove flashy jewelry and watches for the same reason. In the last hour or two before they pack up and leave, sellers will be eager to get rid of their remaining merchandise   The flip side of arriving late is a smaller selection. For maximum choice (but higher prices), arrive early. If the flea market is seasonal, the time of year can also have an effect on the price. When the flea market has just opened, sellers will have a large inventory from the off-season and may be eager to offload it so they have room to obtain more desirable goods. Once you've found your item, decide to yourself what you're willing to pay for it. Having a clear boundary will prevent you from being convinced to pay more than you are willing.  Never reveal this price to the seller! If you do, he has no reason to offer you a lower one. You can try browsing around first to get an idea for how similar items are selling, but there's no guarantee you'll find anything comparable, and the item may be snatched up in the meantime. Most vendors expect haggling, but offering less than 50% the asking price will only offend them. Asking for a 25 to 50% discount is usually considered reasonable as an initial counteroffer at a flea market, although the final price will more likely be 10-25% below the listed one. Saying "hmmm" or simply pausing before you reply will make you seem less willing to purchase the item. This gives you more bargaining power.  Simply remaining silent can cause them to respond with a better offer. This works better if you have the seller's full attention. If you're trying to buy a $1 keychain, the seller might just ignore you and move on to another customer! After a pause, respond with a new offer between your last one and the seller's current offer. Continue to show hesitation until the seller reduces the price below your secret "maximum price". If the seller won't reduce the price to that amount, try these other tactics:  Agree to their last offer on the condition they throw in another item you're interested in for a reduced rate.  Have a friend pretend to pull you away or convince you to move on. This may trigger a final offer from the seller.  If you don't have a friend handy, simply start walking away for the same effect. Once you try this, though, you won't get a better deal if you walk right back to the stall! Pull out the amount of cash you're offering and show it to the seller to tempt them directly. Don't try this with a large amount of money, or anywhere with a high risk of pickpocketing or mugging.

SUMMARY: Dress down. Arrive at the end of the day. Secretly decide on a maximum price. Make a low but reasonable offer. Show hesitation before responding to their counteroffer. Continue negotiating until you agree on a price or the seller balks.

Q: There are commercial stretch wraps that are made specifically for wrapping luggage. These rolls of stretch wrap are designed with big handles to make wrapping your luggage easy. Many are also brightly colored, so identifying your bag after your flight is very easy. These products are available from online retailers and at select some big box stores. When wrapping your own luggage, you can also use industrial stretch wrap that is used for wrapping pallets and commercial goods. This cling wrap is stronger than that sold to wrap foods in homes and restaurants and comes in longer rolls. Commercial cling wrap is typically available from packaging supply and moving supply companies, as well as from online retailers. When planning out what to take on your trip, remember to bring your plastic wrap with you if you want to wrap your luggage on your return flight as well. However, the wrap will have to be transported in another piece of luggage, as you can't get it into a piece of luggage after it has been wrapped. Some people are hesitant to wrap their bags in stretch wrap because it wastes a lot of plastic. If you are concerned about the waste but still want to wrap your bag, you can recycle the stretch wrap at a recycling center that deals with that specific type of plastic.
A:
Use plastic wrap made for wrapping luggage. Purchase large commercial stretch wrap. Bring the wrap with you for your return trip. Recycle the plastic after use.
