whether people know it or not, the weekly shop is partially revolved around players anyway. if you're asking around for a specific item, or mega stone, its quite likely it'll be in the next weekly rotation. For example, 2 weeks in a row, I've been looking to buy specific items, and both following weekly shops had them sold. just asking to buy stuff while helpers and up are on relays the need for that item to the staff team so they can plan the next shop accordingly
