oh, now, that's just silly.  most retailers these days actually disclose what goodies one receives to entice you even further to participate.  whilst i've heaps of appreciation for the freebies that merchants attach to certain purchased items of their [non-grab bag days since this event doesn't require specific items to BE purchased aside from price], and i can appreciate the idea here that Rendo is leaning towards, i do think this could've been organised or thought through better.

thanks for the info, zicsov, of the apparent randomness.  i know if i had more control, or say, over what i might receive if participating, i'd most likely be making a number of purchases today.  like you, my needs/desires for certain types of things is within defined parametres.

plus, that kind of offer of choice would also mitigate the need to turn off the 'already purchased' feature.
