Hey I bought my exo terra 36x18x36x last week and the guy also threw in a 24x18x24x one except it's missing the top, does anyone have one that they no longer need or use? Amazon has them for like $30 plus $15 shipping. Exo-terra said they'd send me one for $40 + $12 shipping, I kinda don't have that money to throw around right now but I want to start building both of them soon. Let me know, I will gladly pay for shipping
