Thanks for posting, wee-haggis! I went in to our Ardene's here and got 4 sets, but I didn't get the great deal you got. Mine were 70% off, regular $11.99. I paid a little over $16 for all 4, tax included.
I chose 2 Tinkerbelle (White with pink trim. Embroidery says "No such thing as too cute!"), 1 purple/mauve stripped with Winnie the Pooh and flowers embroiderd on it, and 1 bright yellow Sponge Bob (for my son who will be 10, since he wouldn't be caught dead in a Mickey hat with sparkly red sequins!)
2 of the hats sets are for my kids for our Dec trip. I'll just put them in the backpack in case it gets cold watching parades in the evening. The other 2 sets are Christmas gifts for my husbands nieces. (They'll think we got them in Orlando!)
