Hey there!
I've got 2 extras right now. Both are gently used and are themes for little girls. One is princesses and the other is stars on a yellow/pink background. I'm in Garland-not too far from Richardson. Just a thought... Shipping wouldn't be much as they don't weigh much although the package might be bulky but I bet I could come up with a creative solution. *Grins*
Otherwise, you can look online at Pennies. Some Wal-marts carry plain plastic matts that have a lot of cushion but aren't very cuddly. I chose the ones I have because there is an attached pillow, and cover and it all rolls up and stays rolled with velcro tabs. Both have a strap attached that makes them easy to carry.
Shipping from stores is usually around $15 or more which rivals the retail price. I paid retail because I didn't know where else to get one when my first child started preschool. Once Upon A Child would be a place to look or JBF which is Just Between Friends and a sale of gently used tons of child related items... Try JBF.com or justbetweenfriends.com.
Good luck in finding what you need and if you're interested in either or both of mine do let me know and I'll do what I can to help you. Heck I'd sell both for $10. just because we don't need them now!
