Free into Store (FIS) is an unofficial trade term that indicates that the seller's price includes all costs associated with delivering the goods to the buyer's store. This means that the buyer does not have to pay any additional costs for transportation, customs, or other fees related to getting the goods from the seller to their store.

FIS is typically used in situations where the buyer and seller are located in different countries, and the goods are being shipped internationally. In these cases, the seller's price will include the cost of transporting the goods from their location to the buyer's store, as well as any customs or import fees that may be required.

FIS is not a standardized trade term, and its use may vary depending on the specific circumstances of the transaction.
Some sellers may use the term to indicate that they will cover the cost of transporting the goods to the buyer's store,
while others may use it to indicate that they will cover the cost of getting the goods through customs and into the store.

Overall, FIS is a useful term for buyers and sellers to understand, as it can help to clarify the responsibilities and costs associated with delivering goods to the buyer's store.
