I think I may have a shtick to get 100% out of your Zappos, very easy and straightforward. I won't know until the end of the week soonest if it works, but I'll let you know once I know for sure. (PM me if I don't put an update by then.) So I'd hold on to your GCs for another week or two!
What was the shtick?
that post was 4 years ago I doubt whatever the shtick is will still work.
Selling $50 Zappos GC for $45. PM if interested.
