Any advice where to get cheap vet care?

Picked up a stray kitten a few weeks ago. Long term I’m trying to offload it on a friend or relative. I would keep it myself but I already have a full grown cat and full grown siberian Husky… they both love the kitten but especially with the dog its a disaster waiting to happen.

I went on vacation a week or two ago and my brother “watched” the kitten for me, and for a bit it looked like he and his g/f would keep him. But now they’re going on vacation for a few weeks and aren’t sure if they want to keep him.

Either way if he’s going to stay at my apt I need to get him dewormed and checked for feline HIV/etc. I took him to a Banfield Vet (the place inside like petsmart’s) and it cost me $70 to get him checked for ear mites and then medication, so I’d like to avoid that again. Other than just calling around to the local vets does anyone have a suggestion on where I could check. (he’s far too young to be fixed right now so that isn’t a concern).
