This is the cost of doing business... no one forces a store to hold a gameday, so I would hope that by now with all the free D&D gamedays a store knows whether it makes up for this added cost or not... that's what running a business is about... as for "incentives"... I'll discuss that below.
Because you get to sell products a week or more before anyone who doesn't can. And honestly there have been numerous posts by FLGS owners who have stated this has greatly increased their business.
Yes- I've seen them too, and was never indicating it didn't work at all. I'm just saying that this is part of the plan at increasing that business even more.
You don't have to agree with it- I really don't care. My entire point was that there's more to it then simply WoTC wants money.
It's a clear plan of action on WoTCs part to support the FLGS.
Letting them sell material early is part of it. Game days are part of it, and the 6 dollar buy in helps support it.
Yeah, because forcing people to spend $6 on a product they know nothing about and may not like will do wonders for the "hobby". Also because there is no other way to spend $6 and support the hobby... while still actually getting something you know will be useful to you.

... wait actually I listed a few in an earlier post.
No one's forcing you to do anything. The store is holding a voluntary event, and there is a buy in to take part. If you want to take part, you pay the 6 dollars - and you even get a pack of cards out of it.
If you don't- then don't buy in.
Same as if you decide to go to Gencon or any other number of conventions. They all have buy ins, and the buy ins help support the whole thing.

I agree with whomever said that the smart move would be to give the stores some sample cards and allow those to be given away as free samples to go along with the game. That creates an experience that right from the beginning appeals to everyone, thus making the net pretty broad.
Sure- thats a good plan to get people into the stores... But it does nothing to really give the store a guaranteed income from the people who take part. Selling the cards creates kind of a safety net for the store.
It's a known issue right now that people are routinely going to physical stores, demoing the product there, asking the store owner questions about it, and getting the tactile experience, then leaving to buy it on line.
Sure- as Imaro indicates it's part of "the cost of doing business," but if WoTC really believes that brick and mortar game stores are very important to the industry/hobby then they can't just sit around and hope things work out.
