What price are these two shops you're looking at seeling the item you want?
If they're different go into both armed with each others prices and make sure you state clearly "This shop down the road is doing them for X amount, would you be willing to compete with that?" I've done that occasionally with guitar shops (I know it's not hi-fi but retail is retail) who won't even check the other shops price, they seem to know and are willing to either match, beat or add some worthwhile freebies into the bargain on the spot.
It's always worth a try to get the best price but remember, we'd all like things cheaper but like the poster above made the point, sometimes the price you see is the price you'll get, and in these days where products are sold far nearer shops profit margins than they used to be I think it's far more realistic to find the best prices on the net and on the high street and go with what your pocket can afford.
If you can't afford it, wait until you can, or look into other options.
