Alright, so, this June I'm going to a reptile expo in Ajax and I plan on picking up a Ball Python. Obviously by that time I'll have money saved, but I don't want to take too much extra with me to the show because if I do I'll be tempted to wander away from my shopping list and may come home with more than I planned lol.

I have a list of morphs written out that I'm interested in, and what I'm wondering now, is how I can find out how much they usually sell for if they're male (would prefer a male to female, long story lol).
Then, next part, is how much extra to bring for any various supplies I may want? I'm gonna have a tank set up already, but I'd love to pick up an exoterra tank with the opening front (or something similar) to eventually switch my BP into later. Also may pick up feeders, extra decor, blah blah blah.

I've never been to an expo before so I'm not sure how much of the green stuff I should bring with me. People have told me I'm gonna get better prices (on supplies at least) at an expo than I will at a pet store, and other people have told me prices are about the same? I just wanna be prepared is all, and I wanna be able to set up a budget for myself and be able to stick to ot.
