Wow.....what a DB
...... and know that your LDS will charge you more to service things you buy online - so in the end... you don't save anything - and in many cases end up spending more... when you find out parts are no longer available etc... and you have to buy a whole new item.....
This is a broad and very specific to you and possibly you only. Perhaps your shop (you being the proprietor) will knowingly overcharge somebody out of spite but the shops that I give my business to do not. This statement alone tells me you are not the shop that I want to have my hard earned money.
Part of my equipment comes from various LDS's and the rest comes from online. I purchased BIG and small from both.....no matter what I still get my deal when I get each piece serviced. This stands even if I split the service up between two shops simply because it was way more convenient for me.
I really hope you change this policy because you will, otherwise become a "failed business" statistic only.
