Something that everyone should be aware about are payment method-specific savings and offers. Visa, Mastercard, Paypal, and countless other payment options have exclusive savings and discounts attached to them. Sometimes, a retailer provides a deal or discount if you use a specific payment methods, and other times the actual payment company will give you a special offer. Never forget about these opportunities!
Yep! Don't forget to use your store-cards, too, because they tend to come with extra bonuses. Now that I'm living in New Jersey, I'm finding that a lot of gas stations off a discount for using cash instead of credit cards, too. Depending on what your cashback percentage is for using your card, it's sometimes worth using cash instead for these purchases.
The only issue with store credit cards is if you can't afford to pay them off at the end of the month. Otherwise, they're an excellent source of savings! Gas stations do indeed offer a slight discount on cash fuel purchases in many cases. Typically, they charge 10 cents less per gallon for cash compared to credit, although that amount can vary. They pay fees on the credit/debit transactions, which can easily exceed the discount they give for cash payments, so it makes sense for many gas stations across the country to provide this "discount".
Skrill is one such payment platform and I have seen an offer for 20 dollars just to sign up. It is a good gateway for online transactions when it comes to ATM withdrawals charged at a fixed price irrespective of the amount you withdraw. They also charge very low fees to make payments capped at 1%. But the ultimate offer will come from a payment gateway that will accept payments from other platforms with low interoperability charges.
