Please excuse my ignorance, but why do you suppose there is a $100 difference in the price for partial 1/4's?
These are the prices (as best I can tell) from two of the members who advertise here.
The same sort of thing with the trunk extensions, with YO product being nearly $100 cheaper than our members.
Are they really all that different?
I want to buy stuff from our guys, but $$$ are important too!
