I prefer to use TCG Player Low prices instead of Deckbox prices, especially for bigger trades. (Low is super underrated, it's quite litterally the lowest price listed for a LP or better card, A.K.A. the cheapest you could buy it for)

I leave most cards at NM unless they're really ugly, however I will double check all cards before a trade get's confirmed and let you know.

Helpful link: here's a link to the cheapest tracked shipping that I know of: https://www.paypal.com/us/cgi-bin/webscr?cmd=_ship-now
