D&A, BlowoutCards, and SteelCity are the big 3 when it comes to buying recent hobby boxes online. The biggest issue I have with buying boxes on eBay is that there are sellers who pack search the boxes before shipping, if the boxes aren't sealed (or in some cases reseal them, as I had that happen before). In addition to pack searching, the more likely issue is case searching (i.e. a person buys a case and opens boxes until they get the case hit(s), then sells the rest of the boxes on eBay). Not all eBay sellers do this, but it's something to be aware of before you decide that eBay has the best price.
