It's not about whether or not you have free two day shipping with Prime, that only works on sellers that are also Prime.
If a seller is Prime, and the buyer is prime, you will get it in two days. If the seller is Prime, and the buyer is not, it's usually 4-5 days.
If the seller is not Prime, it doesn't matter if you pay for the service or not, you have to read on the sellers site when they will ship the item. It could be 2 days, it could be 2 months from now. Even with a Prime membership and free 2 day shipping, if you buy something from a seller that is not Prime, it still might not ship for weeks, but when it does, it'll ship 2nd day air.
That's why a seller with the Prime logo/icon is at a premium. Because you know you can get it quick, whether or not you have a Prime membership.
