Hey young fella. You doing ok? I like my trufit carpet it is nice. They are slow on email so call them on telephone. (sorry you said to explain it like you are 5)
Seriously but i bought the whole set for $320 late last year and i sold some of the bits i didn't need. Fit is excellent. If they won't post ask (nicely, beer may work) if a club member can assist you with postage.
