FWIW, Sam’s club has discounted cards too and historically you can use a Disney Visa (or other rewards card) connected to the Dosh cash back app and stack the savings. (I can send you a Dosh referral if you are interested.)
Believe the best Sam’s GC deal now is 6.9% off:
%50 GC is 4% off, Disney Visa= 1% back, Dosh = 2% back.
Dosh TOS has always said GC purchases were not included, but when I bought some last year online using my Disney Visa I got the cash back anyway (as have other Liners.)
I bought a Sam’s membership when they had a $10 special, so it was worth it - keep an eye out for those.
Last week I did run a test purchase for a $50 Disney GC from Sam’s to see if I could stack % off using the Samsung Pay app, but so far that didn’t work - and I haven’t seen anything show up in Dosh yet. (Sometimes you have to wait a week and/or give them a nudge - but just want you to be aware Dosh rules could change at some point, if they haven’t already.)
In any case, if this sounds enticing, here’s some captures from my spreadsheet when I was figuring out the best deals at Sams:
