Kmart Garden City have the Rally Deco Duo in stock, but didn't have them put out because the pegs were already full of (regular) Deluxes - they didn't know they were different.
The old lady staff member I spoke to was either really tired, or just rude... I tried being really nice, because I know to her I was just a grown up looking for kids toys for myself. And she just didn't believe me when I told her that they didn't have them in either of the two sections they had TFs. If only I had a verified ID card to show that I know what I'm talking about when it comes to TFs...
