I don't know if this is practical, but it would be really nice to have some sort of credit system for coupon trading.
Frequently I have something someone else wants, but they don't have anything I want or vice versa. If there were some sort of "coupon currency" we could work out a deal where I would send you something for a certain number of points, and later I could use those points to get something from someone else who could use them to get from someone else.
Not only would it help with the "but they don't have anything I want", but it would make trades faster--because a pm back and forth a few times trying to match up wants and haves can take a couple of days if one of the people only checks once a day--and if time is of the essence that can be a day too long.

For example, if one point were worth aprox 10 cents, and assuming a value of 10 cents on the dollar for most coupons, you would trade a $1 coupon for 1 point plus 4 for the stamp=5 points. (10) 50 cent coupons would be 5 points plus 4 for the stamp=9 points. Of course, higher or lower values could be negotiated depending on how hot the coupon is.

It could also make money for the site--have everyone who wants to participate send in $5 for their first 50 points to get everyone started. Buying and selling of points would have to be allowed, but people could buy a whole bunch at a time from someone with lots, rather than sending paypal for 60 cents.
