Best way to ship lots?

[alglossian]

Just looking for the best way to ship "lots" of about 40 and 200 cards each? Do you suggest using team bags, the white boxes sold here? Ship in a flat rate box? Basically, looking to unload my crap from 2014 BC into sets and player lots but don't have the supplies yet and want to buy the things I need the first time. Thanks for your help.

If they are base, team bags inside white boxes inside flat rate works well.

I like to uses flat rate padded envelopes. Yu can ship more in them for the same price as a small FR box
