Ok, I have been allowed to look for another BP for the breeding efforts but I have only $300 max to work with

I was wanting a female pastel or a male spider (eventually I want both for BEES!). Is it even possible to find one of these morphs for $300 or less? I will be looking at the RMRE Aug. 2nd, but somehow I get the feeling I won't find anything for that little.

Can anyone put a bit of hope back into my morph dreams?
