Inventory recently updated. For cards <$1, I may have more than is indicated- I focused on the cards I expect to generate real trades- as my want list is small right now. Almost exclusively in the market for EDH playables- usually for specific decks.
I prefer to use TCG Mid prices to Deckbox market price
<$30 let's use plain white envelopes, no tracking- I can do it for more or less, based on your comfort- that's just my suggestion.
