WTB: Flat Rate Boxes

[newcardsmell]

I am looking at purchasing some Flat Rate boxes.

Now that it is summer my 15-year old is looking to make some extra money.
Usually I just buy local, but it seems like that well has run dry for now.
Anyway, I buy in bulk and then he sorts by team. I give him $10 / hr, and then buy my next bulk and give him whatever is leftover.

Basically I buy my kid a job to keep him busy and making money. He mows lawns and bails hay, but this keeps him busy on rainy days and downtime at home.

What I am looking for:

• 2010 + newer
• Only licensed product ( unofficial product is tough to sort by team)
• MLB only (no USA or College)
• Very few "League Leader" or multi-team type of cards
• I am trying to eventually make all A & G sets, so any Allen & Ginter works.Doesn't have to be MLB

I would like there to be some rcs, inserts, parallels, etc. Not just all common base. I have bought bulk where it was just opened sets that have every All-Star calibur player & RC pulled, so then it was 10+ common base of each no-name player. Please don't do that. I don't expect there to be hobby love guys in there, but I want the people who buy the lots to be happy too. I buy blind for your convenience, so please make it worth it for the next guy.

Looking to buy about 10 boxes total. Up to $50 a box depending on what is inside and if it is Medium or Large. Looking to pay up to $40 Medium / up to $50 Large.

Just because most Dad collectors think the same way:
He collects Max Clark, Elly De La Cruz, Bryce Harper, and Riley Greene if you want to add something low-end to excite him and build his collection.

Anyone want to move bulk product and make some room, and help me help my kid? PM me what you got. Thank you!
