Is there a maximum purchasable quantity limit?

No, there is no maximum purchasable quantity limit on fluid-hub. If the quantity entered in the cart exceeds the one available in stock, you will still be able to proceed with the order: the platform will offer you the choice between a single shipment (when all the goods are available) or separate shipments (the available products are shipped immediately, the unavailable ones at a later time).

Important: by opting for separate shipments, the costs of two or more shipments will be charged instead of just one.
