so I'm looking at my order closer, and even though the website said $19.99, it was still $24.99 in the invoice.
but - 5 sets bundles really did purchase through at just +$30.00. So I got a 5 set bundle for $55 or just $11 a set!
That's Buyer's Club territory! Wish I'd seen that earlier. I'll see if there's interest in the Buyer's Club thread.
Or even if someone was thinking of buying 2 sets, they should buy the 5 sets for just a few dollars more.
