Formica countertops??

I bought a house about a year ago and it has pretty new cabinets but the counter top is terrible whoever installed it didn't do a great job.. my question is i have 12' of counter top where can i get a slab of Formica to install myself? Home depot and lowes seem to only have counter tops up to 10 feet? any ideas? can i put two pieces together or will that look sloppy whoever installed the countertop that is there found an long enough peice.. remember i want to do this for cheap.. do i have to custom order? thanks for all answers
