When it comes to Mike Schley's maps, I'm not willing to pay what he's asking for the full suite of hi-res maps. So, I have two choices: either I change my expectations, or I go without Mike's maps. (Mike also has a similar set of two choices, but I can't make his decisions.) Ultimately, like several other posters here, I opted to change my expectations by only purchasing some of the maps. Do I like paying for digital maps that used to be available as free downloads from WotC? Obviously not...but that doesn't mean I'm not willing to pay for a few of them.
The only takeaway here for WotC and Mike is that my unwillingness to pay for the full bundle and my discomfort about the price of the ones I did buy are both indicators that the price of these maps is approaching the limits of my willingness to pay for these products. (In other words, my demand for these products is highly elastic at this price-point.) Any increase in the price of these maps at this point is likely to lose me as a consumer. Depending on how typical my demand for digital maps is compared to other consumers of digital maps, this could be a sign that WotC or Mike should consider either lowering the price or increasing the value of each bundle. (I'd be a lot happier with the option to just buy a 10%-off discounted bundle of all the unlabeled/player maps.)
