Datacenter proxies are much quicker than residential proxies and are price on a per proxy basis. Most providers will sell these to you in packs of 25 - 100 and will last for a month. Unlike residential proxies, data centers don't have a data usage limit but you are limited the amount of proxies you purchase.
Most users use datacenter proxies for restocks / initial drops on sites that don't have bot protection. Shopify stores regularly restock products without turning on their bot / proxy protection.
For drops where there is bot protection we recommend running some tasks locally or optionally on "clean" proxies which are provided by a very select few providers.
