General guidelines:

I will only ship to the U.S. and Canada, anything else is honestly more trouble than it's worth, especially since I'm not exactly trading $200 cards here. Sorry.

I'll do tracking in a cushioned envelope for anything >$25. I'd expect about the same, but this can be negotiated. Best/cheapest way to send with tracking: print your own USPS label via PayPal:

I'll probably go by Deckbox average price for trade valuation, just for convenience. For higher-value trades, or if you would prefer it, I'll use TCG market. TCG mid is pretty much useless to actually gauge card worth.

I am not a full-fledged store. I'm just a random guy with a full-time job that's trading/selling cards in my spare time. If you want a guarantee that cards will be shipped within 24 hours, go to TCGplayer or something. I'll do my best, but don't message me after one day asking if I stole your money.

Happy trading!
