Just a few random thoughts.....
I'd suggest that those of us not in the pilot program not worry about the changes. First of all it is going to take quite awhile for these pilot store/districts to get things all figured out. The bugs of this pilot program will have to be worked out. They are also going to run in to issues that no one has anticipated. Things will have to be fixed/changed/gotten rid of....and then they'll probably try to roll out this to all stores.
Keep in mind that Spot has tried other things and after the pilot program has been run they stop it. So, don't get too hyped up. It will, more than likely, be quite awhile before this gets ready to be rolled out....if it does indeed do what is expected.
Even now the E2E program isn't what it was expected to be....and this has been in the works for quite some time....
Just think about some of the recent things they've tried....pre-paid Target RedCards, refillable gift cards (you know, the black gift cards at registers), Red Perks, trying to be able to get debit cards at the store without a check, Canada, all the designers that they've feature for example: Lily Pullitzer, Missoni, the store from New York (the one that was in the colors of blue & white) and I'm sure that there may be some other things that they've tried.
Right now they are in the midst of making drastic changes to the appearance of Spot's stores, closing stores in Minnesota and trying out this new Target Red discount cards, still working on getting Cartwheel figured out.....(and of course Cartwheel isn't as good as it was when it first started).
So, try to be patient and don't worry about crossing this "bridge" until we all get to it.
