Maximize appliance purchase

SO and I are planning to buy 4-6 major appliances and we want to maximize this purchase. Best Buy has the best total price, and Lowe’s is a couple hundred more with Home Depot being the most expensive even though all the items are the same. (They won’t price match on sale items, which they are) Total price is about $5000.

We do want to finance, ideally 24mo but know it may be 18mo.

Debating whether we should get the Best Buy cars or not. I’m stressed out because Lowe’s credit card is a good deal, but I like Home Depot better.

What’s the best way to do this?
