*Please bear in mind I don't play MtG, doubt I ever will, so looking at this from a business angle*
so, tl:dr version is that I'm not exactly flush financially, and want to offset my hobbying costs by a supplementary income.

So I was thinking about buying a booster box, and then selling the cards individually on eBay.
A booster box is ~£90, and nets me 504 cards. If I sell everything at 50p each, I still make ~£250, which gives me a profit of ~£140 (less costs of envelopes for shipping etc)
Probably Lands are going to eat away at that profit margin, but I'm thinking I can bundle those up into 10-packs and sell them cheap.

But I wanted some advice from the more experienced MtG players about the viability of buying cards specifically to sell, is it a bad idea? is there too much risk to make it worthwhile, is the marked saturated with others doing the same thing.

Thanks

The majority of the cards in a booster box aren't worth 50p. The majority of commons(which are the majority of the cards in a booster box) are worth pennies... Uncommons are worth a variying amount but most will be under that 50p mark... Rares are worth significantly more, but the majority aren't worth a ton of money.

If your paying retail on a booster box don't plan to make much money at all.

Yeah, I've just done a bit of ebay scouting.

so much for that Idea...
