KNOW YOUR VALUES I get sale ads via email all the time. Sounds good but if you watch, the same outlet has the same price before during and after the sale. I recently got a subscriber only ad from an online retailer that also has a brick and mortar store through a town I just passed through. So I clipped the coupon, walked into the store rather than ordering on line. Lo and behold, my "special price" was marked on the box for anyone who walked in, coupon or not.
My experience says check the manufacturers suggested retail price, deduct 20 % as a starting figure, then start looking for better savings than that. A 30 % savings off the MSR price should be out there somewhere. THERE IS NO outlet that is consistantly lower in price. (I know you all have your favorite place to shop and buy but take it from this skinflint, there are better places if you look) The biggest consideration before purchase is the STORE warranty. Most reputable manufacturers have a good warranty but it entails shipping, waiting, and paperwork hassles. Some outlets (REI, etc) have their own "no questions" warranty and take care of mfg hassles for you. This is BIG on major purchases, avoiding delays and other nonsense. It is often worth more than a 10 % or more savings for this kind of service.
