Just wondering about price differences

I gotta ask and probably there isn't a good answer. I am getting ready to buy HD springs 1" over stock for the Barracuda need them pdq. I read alot of threads about Espo, (Springs'nThings) so I checked with them and got a quote of 255/pr. plus shipping. So I thought I would check with Eaton springs and found out their HD springs 1" over are 260 ea. we can all add, that is 520/pr. plus shipping. I called Eaton to confirm that price and it is correct. Excuse me but can anyone tell me why the hugh price difference? I understand that not all manufacturers charge the same for like products but is Eaton that much better than Espo?

:dontknow:

I know a few guys who bought the Espo springs and haven't heard any complaints from them.
