Sorry if I haven't reached your level of sophistication but I like to SAVE money which I do at Walmart. My only beef with them is their recent blockage of Samsung Pay.
“but I like to SAVE money”
Now theres a bad habit you need to get rid of. Go on! BUY that Lamborghini! You deserve it! ;-)
First of all Samsung Pay is touchless and works almost everywhere.
The reason I use it is it is secure. They do not expose my real card number. Since my wife and I switched to Samsung pay we no longer get a new card in the mail saying that the current card is compromised.
I don't know anything about Samsung Pay, sounds like walmart hasn't reached a level of sophistication in that matter.
Anyway, the best way to SAVE money is not to SPEND money. Especially at walmart. 8~)
