For a while, you could bang out Costco.com order after order without getting website errors. Well, it turns out because of all the bots trying to buy up Pokemon sets a month ago or so, they’ve now throttled orders by IP address. It seems after 7-8 orders, you’ll get a web site error. You can either wait the 10-15 minutes for it to reset or you can change your IP address by tethering to your phone or something. This will let you to continue to bang out orders. Once you hit the limit again, toggle airplane mode on your phone to get you another 7-8 orders.

No idea why I’d ever need to ramp this up, but thanks. Can you clue us in (besides Pokémon)?
Obviously, any item with limits per order. I just don’t know what would be a good example of when you do so. Guessing gold coins, as you are a high roller.
