With the way most stores guarantee price matching, I don't see the need to send someone on a wild-goose chase.
Most businesses such as Waly-Mart, and the others have regular people on payroll who walk around competition's stores getting this information. They don't call.... it's only published on advertised items, not customized like our
signs or truck lettering jobs.
Suppose for a moment the OP called 4 shops and all of them were back-yard hacks and gave ridiculously low prices..... is the OP expected to drop below them or use their head and stay higher ??
Why not offer a good legitimate answer such as do your own math, put all your costs out there and see what
YOU yourself needs to keep the doors open and go from there ??
Why base your cost
of operation on shops not in your area or not doing the same line of work and really messing up your bottom line ??
Anyway, time will pass and most will forget you ever made this remark. You've given some great information in your stay here.... one bad one shouldn't make them put you into a a bad person's column or forced to wear a dunce's hat.
