When buying Visa or Mastercard no matter the form; physical, egift or virtual it's all about the profit you'll earn minus the fees.
Expounding on
@TheOneWithTheTriplets post,
With Chase Ink Plus or Ink Cash card, you’ll earn 8,000 Ultimate Rewards points if you buy 8 of these $200 Visa gift cards, which is awesome.
Another
example are stackable offers when the stars align:
Office Depot/OfficeMax: Buy $300+ Visa Gift Cards & Get $15 Off
Expired
Office Depot/Max Chase Offer: 10% Back, up to $11
Buy $110 DGC - in-store.
Then comes the cb websites, which are YMMV and the icing.
Very profitable indeed
HOWEVER you need a plan in place to liquidate and that can change without warning.
Utilities - even if they charge a fee, your profit is greater.
Healthcare - full gambit there, think dental, optical....
Pet Care - Veterinarians, Kennels & supplies
These are all expenditures many CC do not offer savings.
