Forget adding "Hard to Find" parts to your inventory, reduce your shipping costs they are outrageous.
I do not know why the sponsors on this board are some of the most costly sites to buy from.
Example:
Order a "Red Clip" from your site:
Cost: $5.10 (Local dealer was $3.00)
S/H: $7.00 (UPS Ground to Houston)
So my question is why is it I should I buy from your site
