Thanks!
God, that $5 sale was one of my best ideas. I should write about it some time.
The $5 price didn't kick in until you had at least 3 CDs in your cart that were in that $5 sale.
So it was a way of encouraging people, who came to just get one album, to browse around and get a few more.
Albums were still priced at $15 or whatever, until you had at least 3 of this sale items, so it could take a $15 order for one CD and turn it into a $15 sale for 3 CDs.
The customers were thrilled. The musicians who got discovered because of it were thrilled, because they opted-in to the sale. (They'd usually do it for their older albums that weren't selling anymore.)
It was a huge win, almost doubled sales, and was one of those things I thought of on a Tuesday, programmed on Thursday, and launched on Friday.
I miss those things. :-)
