Well, that depends really.
Are you looking for steel tracks, or rubber tracks?
Sometimes, time constraints can cause you to be pressed to pay retail prices from a local supplier (or a dealer, in which case you are probably paying an arm n’ a leg for them.)
What’s the difference in retail and buying from a supplier?
You can expect to save anywhere from 15 – 35% off, which can equate to a whopping $100+ savings on EACH track that you buy. Yea, so we are talking like 200+ per set.
Especially with the 323 tracks (some of the bigger tracks you would end up saving 500+).
