Pink Shoes

Fabulous pink shoes.

They cost $49 originally.  When I found them they were $2.99 and it was half-price day so they were about $1.50.  Whenever I wear them, people compliment me and ask about them.  Is it tacky to say how little I paid for them?  Because I'm really excited about it, even after a month.  Should I just smile gracefully and say "Thanks, I love them too"?  

p.s. They're really comfortable.
