I guess I will try it in the morning..
No more than five cards may be used for any single purchase. Discover has Staples $25 GC for $20 CB.
Can I buy several $125 items with 5*$25 GC in separate transaction, then return the item to merge the GC balance into one card (so I can use more GCs)? Anyone has any experience with this?
Staples managers are mostly jerks (at least ones I have dealt with...)...
