The following Everyday Savings Tip comes from, Amberley:
I save money by saving the envelopes that are sent in bills etc. and using them for rebate submission or other types of mailing. I often save part of the packing slip from a package that has no print on it and use that great sticker to cover a misprinted address or a celophane window on an envelope you wish to reuse.
A box of plain envelopes range in price from about $1.50 to $3. I go through about 8 – 10 boxes per year. This year I bought one box and saved those “precious” envelopes for “important” mail saving approximately $30 annually!
