I signed up and I still can't make this work. The website already asked me to register when I used the "SAVE15" code, but only said, "You Have Entered an Invalid Promo Code" when I tried entering "SPRING15". I'm a new customer, which is required for the "SAVE15" coupon, so I'm wondering if you must be a returning customer in order to qualify for this promo. Slickdeals tells me it has an 8.3% chance of success.

That's not the only issue for a Californian. We pay tax on Jet purchases, so there's a $22 premium triggered from the base price over eBay sellers who tend to be our best chance at avoiding sales tax (everygoddamnbody has a physical warehouse here). That's a killer deal, and I envy you, but for now, that $273 figure is the best I've seen with a processor that is at least (if not honestly) sold as "New" here in Cali. There might be a better deal, but $273 new all-in (99.4% positive) with expedited shipping ain't bad.
