I'm amassing gift cards at discount to pay off my DVC dues next time around and also for a little free spend at Disney in November. 3
Best Buy offers, plus the BBB offers and now my one lonely Staples offer gave me $1000 for $890. I need roughly $2900 but have a stash already plus this recent windfall. Some are 5% discount, some 10% and some 20%. I try to work in the purchases in my regular travels and live where there are multiple stores, so I think it is easier for me, plus being retired I have time to spend.
10% of 3k is almost $300 back in my pocket. I'll take it. (Plus add in the credit card rewards on the 3K spend.) In the 'old' days 3k spend on my Amex spg was worth a weekend night at an Aloft or Sheraton on the way to Disney, which was roughly $125- $175 in value so it all comes together.
Your stash should depend on your goals - I'll always or most likely always have a goal of $3500-$4000 in discounted Disney gift cards in a year with most going to dues.
