In Kemco news, looks like the collections are starting ESRB releases. I suppose the LRG contract is finished. Hope you didn't invest in single games at $35+ a pop...

For the
Super Rare Blind Box Sale, I did the math. Based on raw percentages which, assumes all games are equally available in their respective categories, you have about a 50/50 chance of getting game that is "worth your time."
My estimate for "worth your time" is finding the
PriceCharting New value for each game and subtracting $50 off it, which is the assumed cost of the blind box plus shipping. If the remaining value of PriceCharting New minus Total Cost is $10 or below, I think it's probably better to just go grab it off eBay (or not "worth your time"). If it's above $10, then it's probably "worth your time" regarding investing in a blind box.
The $10 or less wiggle room also helps iron out the inaccuracies of PriceCharting in general, too.
But we know the games are not equally distributed. Therefore, if a game that is "worth your time" is only half as likely to be available as games that aren't, you have about 27% chance of getting a game you would want versus just getting it off eBay for the same price or cheaper. If the a game that is "worth your time" is only one third as likely to be available as games that aren't (meaning three crap games for every one high value game), you got about a 17% chance.
So basically, your best case is a coin flip. In reality, you have less than 1 in 5 chance of getting something for under market value, IMO, assuming you even want the game you get.
Essentially, don't buy them. Just go to eBay and buy the games you want.
