I felt the same way you did..although mine was only a 50%...
I bought 4 spools of thread which were on sale and I was able to use my VIP card also........
With the 50%, I did buy Fon's & Porter's white lead pencil for marking. I would never spend $12.99 for it but $6.50, I sprung for it.
Almost everything there was either on sale or I didn't want it !!!
