I have invested in them...I am trying to determine the best way to dispense them amongst us chippers...right now I am selling them for $3 for ten plus some postage, and I am not sure how much because of the size...They are 9" by 7" to fit the #10 envelope, these can mail four + chips....if you cut them down yourself to the small size envelope, it will mail 3 chips and you have a remainder that will fit one chip. The postage savings on this is amazing...you mail according to 1st oz. 41c, 2nd oz +17c, third oz +17c etc...(instead of starting at 80c + 17c etc. I have been using them for about 6 months.
