I ordered 6 Hydro Flask 24 oz bottles because they offered combined shipping ($4.99 for first item, $1.99 each additional item. When I asked for order total, they refused to honor th shipping details listed on the ad. Said they no longer had combined shipping. They then went in and changed the shipping details to $4.99 per item. I canceled my order and bought somewhere else. They should have honored what was listed at the time of my order.
