What's in it for us?
We love you, and we want your business. We don't want you to run off with some other online retailer, so we're, of course, willing to give you the same deal they are. Plus, in the end, our deal will be way better than theirs! We'll match their price while we deliver life-of-product technical support, real customer service, and free shipping.
More Technical Details
To qualify for a Price Match, you must be able to produce a published price from a legitimate online retailer. Hearing about a 'great deal' from your cousin's neighbor's best friend does not count. The retailer in question will also need to have the product in stock and ready to ship. If it's on backorder, that's a mulligan. You get one claim per product, and cannot use the Price Match Policy in conjunction with other coupons, discounts, Labor Day (or other holiday) sales, or Voodoo magic. Typos, mail in rebates, closeout sales, and other non-standard retail transactions don't count either. Also, finding a great deal on Ebay or another auction site doesn't work.
Basically, the competing price must be for the same product, brand new, factory-sealed, style, model, etc etc. We also reserve the right to deny the IWAE Price Match Policy to anyone who we think is trying to get one over on us and/or trade us a wooden nickel.
