well I posted something on this just a while ago with my experience
Herebut I cant answer this poll and convey what I want.
Here is my list of problems:
Availability in a good quantity of stores. The original store I got my last pre-order from did not have the pre-order this time around so I had to resort to EB where I would have preferred to go back to the original store. Doesn't mean it wasn't available to me locally but out of 5 places I could have picked up the package from only one had it (and they didnt have it even on the shelves).
Retailer doesn't seem to be putting these things on the shelves like they were the first time around in last pre-order situation. Its like they are waiting for a customer to ask about it before they hand it to you.
Product knowledge regarding Collectors and Standard. They simply dont know well enough about dates and availability of each and when they will be available or the differences. At pre-order time I think they should. (see also my suggestion of placing that info right on the package).
As I was saying in the above link, put as MUCH information on the pre-order box about both CE and standard and time while you can. Don't rely on these stores to broadcast that information or market the product when you can! That would be my tip.
