and, can understand where you're coming from...I'd venture to say that most vendors are very small businesses, run (as i eluded to before) only on a part time basis. So, vendor A may have purchased more widgets than vendor B...thereby allowing vendor A to undercut vendor B's prices...they all have markups...to cover their operating costs & to make a little profit (can't grow a business by only breaking even)...Also, you know, it may be the flea market-like setting that makes people feel it's appropriate to haggle...
Have you ever seen those pins or t-shirts that say "I buy Black, I give Back"...The Black dollar has power indeed, but I don't think that the whites, koreans, japanese, etc. really fear us taking that "power" elsewhere...because they know that we'll go to joe "white guy" & pay exactly what he has posted as the price...while we'll go to dexter "dred" & ask for a hook up....I believe it's the "my brotha, my sistah" stigma...which, can help explain why you might find customer service and/or goods to be sub-par at some Black businesses...Just because we two happen to be the same race doesn't mean you should put any less than your best foot forward...it kind of goes along the lines of what's his name that sold BET...that was his business, he received a lucrative offer for it & jumped at the offer...some screamed "sell out" & "irresponsible"...but, he doesn't know any of us & wasn't about to allow people who just happen to be his same race dictate how he handled his business...but, I digress (as this is getting off subject).
I commend the BGLO's for supporting & working to make the world community the best it can be, in particular the Black community. However, don't go to your brotha/sistah & ask them to accept less for their goods or services, when you wouldn't ask joe "white guy" for the same.
I plan to start my own business some day, and I pledge to provide the same exceptional service & products to dexter "dred", as I do to joe "white guy"....so long as neither one of them asks me for a discount...
