Sorta but not really a duplicate of this
I've got a credit card that I need to somehow spend $3k on in the next few weeks in order to get my points bonus, but I don't spend that much…
What are some things I can buy but get fully (or mostly) refunded after I get the points?
A hotel room on expedia or booking.com. Look for "Pay Now" and fully refundable. I had to cancel a hotel reservation made through expedia.com.au early last week. I checked yesterday and the money is back on my card.
