Hogwash. I’ve bought tens of thousands of dollars worth of gear from B&H over the last decade and they are as reliable as they come. They do not falsely advertise or try to intentionally trick you.
In the case of new products coming in, they do their very best to forecast the arrival date, but they are a reseller and are not a direct part of Apple’s supply chain so they do not know with certainty what will be arriving on what date. So they try their best to estimate it for you.
In this case, I can also confirm what Chris said a couple posts above. I just got off the phone with B&H and they said that they were expecting iPads to arrive today, but they did not come in. He spent some time in the inventory system and then spoke with the wholesale ordering department. Bottom line is they are now saying that it looks like Apple’s supply chain will put iPads in their hands sometime next week, but they cannot say for sure. (This is beyond their control and is up to Apple.) They are not advertising a date now since there is so much uncertainty. It could happen in a day or two. Or it could happen next week. We just have to wait and see.
That’s how it goes with resellers. For those that want more certainty, ordering directly from Apple is and always will be your best option. But for those wanting to save some money, resellers like B&H (and others) are a good option if that is the route you want to take.
