This should get you started (and reference the documentation for more information about SqlBulkCopy):

//you must reference System.Data and System.Xml
open System.Data
open System.Data.SqlClient

let bulkLoadUserPurchases (conn:SqlConnection) (userPurchases: list) =
    use sbc = new SqlBulkCopy(conn, SqlBulkCopyOptions.TableLock, null, BatchSize=500, BulkCopyTimeout=1200, DestinationTableName="YOUR_TABLE_NAME_HERE")
    sbc.WriteToServer(
        let dt = new DataTable()
        ["UserID", typeof
         "ProductID", typeof
         "Price", typeof]
        |> List.iter (dt.Columns.Add>>ignore)

        for userPurchase in userPurchases do
            let userId, productId, price = userPurchase
            let dr = dt.NewRow()
            dr.["UserID"] <- userId
            dr.["ProductID"] <- productId
            dr.["Price"] <- price
            dt.Rows.Add(dr)

        dt)
