You should probably just put more effort to doing better at your day job and earning a promotion.
Btw, some just Business 101, sitting on the shelf is inventory cost. Inventory cost is horrible. It decreases free cash flow and increases risk of obsolescence. These are real-world costs to getting the "most bang for your buck." If you're going to buy shit for resale, it's always better to look for stuff that can be liquidated in, say 5 days, for $10 than something else for $20, but will take a few months. Turnover is critical.
Lol, ok. I don't run a business. There is no "shelf cost" as it is in an unused room. Also, my day job goes just fine and I had a promotion less than a year ago and I just hit my 1 year mark with the company a little under 20 days ago.
You guys are nuts if you think like this. Not everyone needs the "business" mentality as it certainly isn't my life's blood. Besides, if I were a huge reseller, I wouldn't buy only 1 copy to flip.
