They sent an email every 1-2 days since the announcement of the price change. After a week or so, they changed the email category from "Promotions/Marketing" to "Important Account Information", so they could respect user email settings while still spamming them daily about the pricing offer.

To me, being asked, "Hey are you gonna buy this? You've only got a month, come on, buy it already!" on a daily basis qualifies as a pressure sales tactic, no matter how good the deal may be.
