Everybody needs to remember a good deal is a state of mind..........
I have purchased via gunbroker.com a few items, deals went thru. Also have used other BBS.com sources with success. Like everyone, always looking for the best deal (price) for the item. Not all sources of goods live up to expectations (price, time, availability, quality, etc.). Unfortunately the www presents so many options on sources, it is difficult to find a single source in a competitive market.
After calculating sales price, shipping and ffl cost, to me it is a better deal to work the price with a local dealer that works with you on availability, price and service.
