I can say most of the "Apple" Best buy employees are idiots.
Two days ago I asked the same question about stocking the 8GB/256GB 13" and she told me she could upgrade it in the store. Of course I had to remind her this was an Air and the RAM is soldered in. A sort of puzzled look ran across her face. She wasn't even sure of the current specks of the display models. If this was an isolated incident, I could understand but it seems to be more of a rule for Best Buy employees.
 
re best buy

The nice thing about best buy is that with their extended warranty you can get replacement items with little hassle

However, they don't know all the ins and outs of apple products. Get your information from the Apple Store Geniuses before you buy at Best Buy
 
Be careful on the extended warranties from Best Buy.
Some of them are one use only. Meaning that is you take it in for service you will have to purchase another warranty. Not sure which one they attempt to push with a laptop.
