So how about try this.
Buy two things each worth around $110. Pay first $20 with a debit card and then after that the gift cards. When you go to return ask that everything be put back on the first card
If that doesn't work you can try returning each item separately and each time hopefully they will put it back on the first card (the debit card)
First of why does it have to be done with a debit card - and not a cc?
Second off all, it will say clearly on the receipt that I used a gc for $90 of the purchase, wat makes u think they gonna be willing to put everything back on the first card?
I appreciate your suggestions, but I just don't think they gonna work.
Btw lowes is pretty sophisticated when it comes to keeping records of purchases/returns.
