I did it. I actually canceled because I never rec'd the product during the trial period. I did finally receive it a month later! Everything went fine no problems at all.
FYI, I did this one and got credit for it. Canceled within the proper time frame (never did receive the product within that time frame). Just saw my CC got charged today for the full amount... $54.76. I have my cancellation number and am on hold now to see what the deal is.
