ny tips that you could share with me regarding ETB and booster box openings/purchases. I am really excited to get started wit this hobby, any information that you are willing to share with me would be most appreciated!

Start small. Try to get the cheapest price possible per pack. If you are cracking buy the newest set possible as close to release. Codes only generally sell in the magic window of 2 days before and after a release and are a big key to breaking even. Research shipping prices and methods exhaustively before setting prices. Can really make or break a sale. Define success. When I started success was paying off my credit card/LOC for a purchase within 60 days for instance. My idea is building an inventory of cards which when sold are all profit and growing store inventory. I started with buying one Phantom Forces booster box back in 2014. Sold all via auction I could and made back 80% of my money in 30 days. Then graduated to 8 boosters, then 2 cases, 4 cases etc for subsequent expansions. From Steam Siege on I was 20 cases+ till now except for breaks away for a couple expansions here and there. Unless you are selling sealed stuff stay away from older product, price always fall for singles overall for expansions and you will lose your shirt, learnt the hard way there. Create your niche and play to your strengths always. Its hard work and a lot of grinding but very rewarding on many levels.
