This is an important week for Baseball card collectors. This coming Wednesday is the official release date for Topps' 2018 Series 1 flagship Baseball card brand, so you should expect a flurry of post about the set over the coming days. Go here to check out the entire checklist. As an incentive to visit a hobby store, a limited number of 2018 Topps Series 1 promotional Silver Chrome packs are available when you purchase a box at your local shop (only) -- so, this isn't available at Walmart or Target.
How it works is for every box (hobby & jumbo) that you purchase at your local card shop will get you a certain number of these packs.
