You'll want...

Walmart....
15 or 28 quart tub (for a young bp)
an indoor/outdoor thermometer and hygrometer (Accurite)
plugin lamp dimmer (not sure if this is available at walmart, but can find at Lowes - most decent thermostats are usually only found online)
soldering iron
water dish

Petco or equivalant store...
undertank heater
two small hides (can also get rubbermaid like containers and melt holes)
aspen bedding or just use newpaper

I think that the most basic stuff. I hope this helps.
