For any store owner, this is a "must have", which I hope it will make it for you a "must buy". Available 79 plastic bags just like the ones in major grocery stores. They are all brand new, still clinging together, ready even to be hung on your hooks so that you will tear them apart one by one. They are 12" wide, from bottom to top handle 21" long, from bottom to mouth 15". On each side there are two flaps that, extended are 7.5" wide. And, I hope I am technically correct, bottom is one seam heat-sealed.
Shipping cost, the most you will pay, will be $4.95 as they will fit in an Flat Rate Envelope. But if using a normal envelope or box, especially if you are close to MI will be less, I will use that approach.
Since they are plastic, and since I do not need them, I prefer to recycle. Starting price is about enough to cover all fees if they sell, E-Bay and Paypal. But don't let this stop you to spend a fortune on them.
I've been asked for shipping cost to Canada. Took them to Post Office and found out, anywhere in US will be $4.95, cheapest rate, and for Canada is $5.99
