What should I say, if for cheap stones you are willing to sell your diamonds then go ahead.
You can get 50k in one shot when you use it for a minimum spend VS. a few bonus points by liquidating a GC...
So you think if everyone goes in twice a month, does the 5k it will last longer? What happened to BB... It will not make a diff, in fact if everyone who liquidated gift card, pushes debit it may even last longer.
Just don't go when its super busy and the cashier will not mind watching you for a couple extra minutes.
As for me, I do not liquidate GC in target.
