When shopping on SendToPhil, you can add things to your Cart by clicking on the item you want and then clicking on the Add to Virtual Box button. The item has then been added and will appear in your Cart.
Please take note that air freight and sea freight boxes cannot coexist in the cart. You will not be able to add an item (with a sea freight option) to a cart that is in air freight mode. In order to add that item, you must first remove the air freight virtual box from the cart.
There are some items on SendToPhil that do not have an Add to Cart. These are items such as flowers that have a Buy It Now button instead.
When editing your cart, you will see the (+) and (-) buttons which will change the quantity of that item by either increasing it or decreasing it. You will also find the trash can symbol which you can use to remove that item entirely from your cart.
