John,

I have only bought bubble mailers a couple of times. I usually recycle the envelopes that others have sent to me. When I do buy them, I buy them from Staples. The smallest size they sell in my local store is 5 x 9, that costs about $5.00 for a package of 12. I know they are available much cheaper in quantity, but what would I ever do with a box of 500 of them? That would be a lifetime supply for me. If anyone wants to split a box, let me know. I would probably be good for a hundred of them.

I would gladly put myself on the list of those who overpay for mailing supplies because they buy in small quantities. Who is maintaining that list?
