Best Purchasing Resource?

We are changing out all appliances in our '68 Tradewind remodel. We listed out all the items and searched the internet with pricing from Adventure RV and American RV. We also contacted two local sources. Adding shipping to the internet companies brought them very closely in line with the local sources with the exception of a couple of items.



My question is what was your best purchasing method? I am leaning toward the local resource. I have put it out to "bid" to the local vendors and they know I am looking on-line. One in particular is willing to offer additional discounts off retail and will include shipping if we are purchasing all or most of the items.



I don't find the cheapest price to necessarily be the best value. I think with appliances there merit in using the local resource so that i can walk in and deal directly on any issues.



Any comments on the following appliances? The range is a closed burner that has great appeal to me.
