There are no longer any gaming laptops using an Intel Core i3 processor. These days, many entry-level computers come equipped with a 4-core Core i5 processor. However, the most commonly found processor in this type of laptop is the Core i7. The 4-core Core i7-7700HQ processor is slowly being phased out in favor of the Core i7-8750H (6 cores at 2.2/4.1 GHz) and the Core i9-8950HK (6 cores at 2.9/4.8 GHz).
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
