Got an email yesterday from Costco that the $500 value for $450 deal is back. Tried several times yesterday on my laptop and no luck - it just gives a generic message and says the transaction could not be completed. Went to my local warehouse and apparently it's only online. Tried again today on my laptop but no luck. Tried on my Android phone and it went through so fingers crossed I'll get a code (that works). Once in the past I tried to purchase this and it went through initially but I received an email a couple hours later saying it had been canceled with no reason being given. All the problems with this are pretty ridiculous.

If it works the deal is pretty good - 10% off from AS, $9 back on my Costco membership and $6.75 in rewards from my Chase Sapphire Reserve ($4.50 @ 1.5X redemption) So, $500 for $434.25 = 13.5% off.

The deal says no expiration. Does the credit go into my wallet once redeemed? If so, does anyone know how this works with wallet credit? First in, first used I'm hoping/assuming? I'd love to buy a few more of these but don't want my wallet funds that do expire to get buried.
