Wow, I could not agree more!!! The have been the most dishonest company i have ever dealt with in my 50 years walking this planet. The worst part about it was that I refered two friends and my brother, all of which had horrible experiences. I of course referred them before i had my dozen horrible experiences! I refer to them as the "buy here/pay here" Apple reseller. ( like the cheap/slick used car salesman who will lie about everything just to get a sale!)
I would pay full Apple retail + sales tax, before even considering Macmall with no tax!
I have been buying all of my gear from B&H since 2009. Have spent about $10,000 by now at B&H. There's no electronics vendor better than them. They beat Amazon every time by price. Their customer service is stellar. They don't charge sales tax in 49 states - the only state they charge it is NY. They ship for free. They throw in free Parallels with a new Mac. Quite often, you can get Apple Care with a new Mac from them cheaper than you can get it on eBay.
They have custom configuration Macs, which Amazon usually does not. They get new Macs and iPads within a week of them being released. For example, the only place I was able to order a retina iPad mini last week was at B&H. I ordered it last Friday afternoon right before they closed for Shabbat, and it was delivered today (Wednesday) to Atlanta, GA. They had 128 GB cellular iPad Air ten days after it was released by Apple. No other reseller that I know of had them at that time.
By the way, B&H is the largest independent electronics store in the US, and if you are visiting Manhattan, you should really drop by their mega-store. This company provides and amazing value and and incredible customer service.
