This time of year nearly any sporting good store should have tents on sale good for a season or two, well under $100. Here we have Big 5 that usually has a large in stock supply... we have Bass Pro Shop and REI. I still use REI an then Big 5. If you have the time, might get a good deal for a higher end tent online.

Whether it keeps you dry is up to you:

Current clearance on a Coleman 7" x 7" dome tent $29.99

Looks like you have Big 5"s in Texas, Order online they have $10 off first order and free shipping on orders over $50.
