For those that received cancellation coupon codes, check the actual value of the coupons in the cart. Most of mine were quoted at $5-$10 in the emails, however i just found out 2 are actually $45 each... Was just making a purchase intending to use on a small $20 set for in-store pickup, and bam it came up as $45 discount, checked the rest and 2 of them came up as that, nice unexpected find haha.
Issue with these coupon codes is that if they take your order below $50, it doesn't give the free shipping, so I've been using in store pickup when available.
Edit: Make that 3 $45 coupons, they seem to all have been the most recent ones received.
