I agree that if someone has to get out their credit card, they're likely willing to pay more than $5/yr.

The key question here is what percent of the potential purchasers already have a Chrome wallet (or whatever it's called now) and just have to click "buy".

Impulse purchases by these users would be more likely to drop off with a price increase.
