I had previously ran a post on The Walking Dead #115 NYCC Variant from TFAW as a flip idea. They were selling them for $2.99 and they were going on eBay for $20 plus at the time. Well here is another one (or just one to hold on to until the movie comes out.)
You can get Daymen #1 SDCC variant for $7.99 from Things from Another World for $7.99 plus shipping on pre-order. They are going for $20-$30 online. The SDCC variant is limited to 500 copies. Better jump on this one fast before they are gone.
