Look at a few ‘second tier' suppliers, Craigslist, eBay etc. If it's front wheel drive you could get two new tires, then leave the best of the rest on the rear until Winter. I split the baby fairly often, doing it now.
I have two vehicles that I plan two new tires on each before any snow comes.
If over 7 years old, some shops may not want to mount the tires.
