How long ago was that? I have some OM gcs that I got last year and the cashier said no go on buying gcs with om gcs. Wouldn't even try it........... said the register wouldn't take them. This was at a store that gave me no hassles in using rewards to buy gcs when it was allowed.
This was end of October of this year that I tried it.
I was able to do it last month.
Thank you for those who share deals, and for helping me to become a more frugal shopper!
