Fair warning to anyone planning to wait until the end of June to "use up" their 5x capacity with Costco Cash Cards: To meet min spend on another Chase card, I placed an order for a Costco Cash Card on costco.com on 3/3 that ended up with a 3/8 transaction date and 3/9 posting date. YMMV, but the message is, you should probably order by ~6/23 to be safe.
