The Staples return w/o receipt is partially dependent on the amount of the return.
Sometimes I’ve needed to return something paid for with Staples Visa Rebate Card.
Since they can’t refund money to the card, SM has done a return w/o receipt and given me a Staples gc instead.
I asked about being “blacklisted” from returning things and he told me that 1) I don’t do it that often and 2) the dollar amount of my return was too low to matter.
I would never buy something at one store to return to a different company.
I buy things with the intent of returning when I’m “moving stock”. For drug store deal I might need to purchase 6 widgets at once but there are only 2 are in each store.
I’ll buy 2 at 2 different stores, paying full price (no rewards card) and charge to cc.
Then go to store #3, return the 4 from other stores and buy all 6 together to earn whatever I’m trying to earn.
