Expect them to take your money, "process" the third-party transaction, delay for a couple weeks, then inform you the product is temporarily unavailable and grudgingly refund your money after dragging their feet.
We have bought a Tablet and microphones that way through the online service. No issues what so ever. They are like Amazon. A 3rd party vender sells them at a discount. Easy. And you can return it. I picked up both things at Walmart one they shopped them. No we did not have them ship them to the house. Went in the back and picked them up.
