Ok, here's the whole thing:
go to the staples web page and do the search for the memory, click on the link to see the results and click on the only listing that's there to see the product number below the image block.
Open a new window and go to the Crucial site and take note of the price.
Open yet ANOTHER window with the coupon site (one of the two provided in the original posting) and take note of one of the $30 off $100 codes.
When you call 800-3STAPLE and get a rep on the phone, they'll ask what you want. Tell them you want to do a pricematch for some memory. They'll ask you for the product number and they'll ask how much you saw it for and where (the web site). Then they'll put you on hold and make some phone calls for about 12 minutes or so. When they come back they'll tell you what their decision is (depending on whether or not you gave them the correct info). Then they'll tell you the price. Tell them you also have a coupon code and give it to them when they're ready. Ask them about shipping. I've heard different stories on the shipping, but what you want to try to get is the FREE NEXT DAY that is offered at the bottom of the Crucial web site. I wasn't able to get it, but apparently it differs with different reps. Verify everything with them to make sure you understand how much the final cost will be and then they'll ask if you want to order. If you decide to order, you'll have to use a credit card and they'll take a few minutes to set up a profile for you. And that's all!
Correct me if i'm at all wrong, please.
