While I am not the final word, Tony, it is my understanding/interp that what you have done is fine. If there were a problem with the format you've chosen, you would be privately contacted (as a gentleman should be) with a kind request to modify your link (we try to avoid the S.W.A.T. team mentality ).
We've tried to keep the guidelines for such things as simple as possible because we've found most vendor-members that do participate here to be unique from each other (some with actual stores, some without, and many other nuances) which prevents the application of a truly standardized/all-encompassing set of guidelines.
Ultimately, we wish for the Buy/Sell/Trade forum to not be an income generator. Repetitive sales of this nature belong in the Shopping Forum.
I hope that this helps to shed a bit of light on the subject.
