Good catch, if only it worked!

I get all the way to the payment confirmation page for the 55-300 PLM from Adorama, when I get

"We're sorry! This coupon cannot be applied because the coupon usage limit has been exceed." (sic!)

Seems others have the same issue, see here.

I looked at reviews for Rakuten and then for adorama and decided not to risk a headache. Great deal if you can get it.

Coupon is apparently dead and no longer advertised on their front page. Looks like they had a low limit on the maximum number of coupon users, even though the expiration date of 9/19 was suggesting it was going to be available to many, and this was just a ploy to get people to sign up on their sh*tty site.

Too bad if it's not working. I've bought through Rakuten (Pentax MX-1, a kit lens, etc.) a number of times in the past and never had a problem and did take advantage of their coupons.
