I'd say pick it up. Around here, that's about what a seemani goes for, and that's still a decent price for a chromatus. Work on the 100% identifying it later.The thing is I am not 100% on the species, this is not a very educated, so to speak, pet store. They have it as "Thai Zebra Birdeater", one of those weird names they give T's.. I have googled that and B. Albo's come up, which is certainly not what she/he is..
I'm going off of looks, looks of a T curled up in the corner trying to burrow into mulch. All I could really see well were the thick, striped legs. Looks a little underfed, and no doubt he/she is too stressed to eat..
What other T's have similar markings? I couldn't get a good view on the abdomen, but the legs were just like a seemani/chromatus, and very thick, stocky legs like a Blondi.
I can try to get pictures of the critter tomorrow and get opinions.
I really don't know much about them.. just from my quick researching it's said 3-5" is as big as they get.. With his legs spread he's probably 4"..I'm like 95% sure thats an Albostriatum. Notice the classic Haplopelma broad carapace and long gangly legs. I'm also pretty sure they can get quite a bit larger than 3in. If its indeed a mature male, you can just check check for gloves to be sure, but remember that albos dont hae tibial hooks so dont let that throw you off.
