Like someone else said - there is no debate. My guess is that you would have a better response to your 'logic' if you hadn't mentioned that you totaled up your receipts and spent xxx.xx at BRS (which to me makes no difference). Even then, its a specious argument, we are only hearing one side of the discussion (i.e. no one knows how (or if) you were rude to BRS - whether they apologized, offered to do something else, etc when you called to complain). BRS did what every other online retailer would do in this situation, and you got your parts.
You say - BRS is making a big deal out of a 35 $ charge - well conversely - so are you - is it really worth the 'good debate'? And BTW - I dont work for BRS, I have had the same issue with other vendors - and had various experiences (I once bought a $500 light from Amazon, Thought a piece was missing, they sent a replacement light - I subsequently found the piece - called amazon - they said - keep both lights - though it was MY mistake) - And had a much different experience with a different (smaller vendor) who sold a defective lighting controller and I needed to ship the whole thing back at my cost - and wait for a new light)- while my tank had no light for a week. So - all in all you were treated fairly. BRS is not amazon - and treats everyone the same - according to their policies - which are posted on their website.
