Grabs have expiration dates?
Gold grabs expire after about a month, while bubbles grabs are live for a little longer. Seasons come, seasons go; such is the life cycle of the grabius spinsaurus.
You can buy or trade items from expired grabs by browsing Storefronts or Second-hand Grabs: Highrise has an active Storefront trading scene, so check it out in case you missed the grab! Browse posts of available items, and item requests, with tags like #sfexplore, #selling, #buying, #trading, etc.
