Charuop,
If this is the same MSC that does this shop in NH, you can see the directions before you accept the shop. Right under where it asks you the date you'll do the shop, there is a link that says "view" Click that link and you can see the form.
How this shop works. You need a laptop or desktop with Windows 7, Vista or xp and it needs to boot. You take it in and they'll run diagnostics ($69.99) You will be paid for the diagnostics. If they determine that memory is needed, you need to buy the memory (not reimbursed). There are a couple of other things they will reimburse for, but I can't remember what. You could reimbursed for up to $150 if I remember correctly.
You have two forms to fill out: one after you drop the computer off and one after you pick it up. The forms are mostly multiple choice and easy to fill out. And this MSC does pay quickly.
