I'm not sure where people are seeing Modern Masters 2017 for less than $250 consistently. I just checked eBay (2/28/2018 @ 5:29PM PST), and the absolute lowest box I see is listed at $235 with 7 watchers. The average price seems to be between $230 and $260. So, great for you if your local game store sells them cheaper, but for most people this doesn't seem like a terrible Drop
