Amazon, the store for all your everyday purchases: groceries, toilet paper, DVDs (those are still a think, OKAY!), renting movies on Prime, underwear, company hardware, Fleshjacks, TVs, gym equipment (so you can work out to get in shape before going to an actual gym), household and kitchen electronics, lube, spakers, luggage—basically everything including the kitchen sink!
Amazon's whole personality is "we will sell you anything and ask no questions." Groceries, a lawnmower, a Fleshjack—all next to each other in the same cart, all showing up in the same anonymous brown box, all covered by the same 30-day return window if it turns out you and the lawnmower weren't meant to be. That's the actual case for buying almost anything here over a specialty shop: nobody's watching, nobody's judging (well aside from the workers in the warehouse, and the algorithm genuinely does not care what you searched for at 1am.
The largest online retailer, Amazon sells everything at unbeatable prices.
