I have to order my rodents online, order smaller quantities, and suck it up and pay the shipping costs. I can pick up frozen rodents at the closest expo to me if I'm able to go that month, but that expo is 2 hours away. When you figure in the cost of gas, its about the same price as the shipping. I'll do that if I'm there for another reason, but it doesn't always work out that way.

I order my rodents from Layne Labs. They have been absolutely wonderful. The rodents are positively the best quality I've ever seen - clean (pristine actually), large, and dry. They are frozen individually and laid straight with legs tucked back and tails tucked under. No contorted frozen rodent bricks to break apart whatsoever!

I order in 50 counts which work really well for 1 BP and 1 boa (for now, lol). But you can order in as small a count as 5! Of course, the shipping does add up, but they aren't too bad. For my BP (she eats 2 jumbo mice per week), I pay about $78 including shipping for 50 mice and that's only about .65 per rodent shipped! I think that's pretty fair for having the convenience of them being delivered to my door.

Also, I see you got your BP feeding well, but be warned, snakes view rats and mice as completely different prey items. Just because she's feeding well on mice doesn't mean she'll take a rat with the same gusto. Personally, I'd try to find a couple of rats from a local pet store first even if they're a little more expensive per rat. That way, if she won't take it, you don't have a freeze full of rats you can't use. That's why my girl is on the jumbo mice. She's a powerhouse feeder, but show her a rat, even scented, and she says "NO WAY." Layne's jumbo mice are HUGE though. Ella will take 2 which easily equals a small rat in grams. It works for us. I hope all this info is helpful to you!
