US utilities typically sell scrapped distribution transformers for around $4 per kVA. This price changes with the market value of core steel, copper, and other salvagable materials inside the transformer. Utilities only want to sell them to responsible vendors who can document the trail of where the transformer and oil goes.
If you're only looking to purchase a few transformers, then contact one of the used transformer vendors (who typically buy them from the utilities). Perform an Internet search on "used distribution transformers" and contact one of the vendors.

IRV S: there are no PCB's in any pole mount or pad mount power distribution transformers. The manufacturers are required by the utilities to certify this and exhibit a high level of paranoia about any oil in returned goods possibly contaminating their oil holding tanks. Very old medium voltage and substation transformers are the only ones that contained PCB's. The oil in distribution transformer is a very pure mineral oil.

In the olde times, ham radio operators could buy them or get them freem from the surplus/salvage function of the electric utility. Check out your utility to see if they have a salavge yard. The hams took them out of the cans and used them for HV transformers for their transmitters.

You must have no plans for the future.
Using these at the utility primary (12.5 KV line-to-line is typical) is stupid and illegal; using them to step up voltage on your side (240V) would be very dangerous also. One wrong move and they are contacting your next of kin.
Leave these things to the pros, please.
