You do not need to buy the $29.99 shipping if all your orders are over $250.00. However to guarantee the shipping date you can check out with the $1.00 shipping date item. It appears Monday is sold out already. https://www.tidalgardens.com/misc.htmlI also spent more than planned, over $250 but made all my purchases using the "In-Store Pickup or Adding to order" option. Would I need to purchase a shipping module? I would like them shipped. Thanks.
