Using a debit card does absolutely nothing for your credit score, it doesn’t even show up on a credit report.
Can’t understand why anybody uses them.
Using a credit card (getting rewards) and paying the bill in full each month costs you exactly the same as your debit card purchase, maybe even less if you pay debit transaction fees, AND will raise your credit score when used responsibly.
If you time it right, you can earn interest on the float for up to about 6 weeks too.
The credit cards that I like are Southwest Airlines card for free airline trips, and a Norwegian Cruise Lines FREE card that gets you a $500 credit towards a cruise after spending around $17K.
In Temecula, Hwy 79 south exit, (Pechanga casino exit) right on the west side of Hwy 15, there is a SHELL gas station across from an ARCO.
SHELL is usually the same price or a penny less than ARCO, and accepts all credit cards. It’s the consistently the cheapest station that I know of.
