Here is my first reply to the "Helpful Household Tips" topic...
Alliance Supersize Rubber Bands (24 pack)
I found these at the now-closed local Office Depot store in May 2015 for ~$16 which works out to 67 cents per rubber band. Ouch! I then* searched the internet and found Amazon selling them for under $9 so I ordered some there:
I checked just now and found that OfficeSupply•com sells them for $4.71 (Product # ALL08997)*** and Sam's Club sells them on-line for $6.64 (Item # 2292)***
Alliance SuperSize Rubber Bands - Sam's Club
*** Shipping is free for most orders over $45, otherwise it is $7.95.
***** Sam's Club offers free shipping for members on this item to your local store in the 48 contiguous states. (Perhaps someone can fill me in on shipments to one's home.) Membership is $45/year but you get a $45 credit if you apply for a Sam's Club Credit Card and place a $100+ on-line order on the day you apply.
The rubber bands are 1/4" wide and come in 12", 14" and 17" lengths. The most common use is to secure garbage bags to trash cans up to 13 gallon (or a little bigger than that) but they are also handy for holding the flaps down on cardboard boxes with a perimeter up to maybe 44 inches.
