After the campaign, to make things easier, we decided to merge products and their sundrop versions in to a single product with sun drop (e.g. now you should have in your cart ISS Vanguard Core Box

(sundrop) instead of the ISS Vanguard Core Box + separately the upgrade to sundrop). We could have done this only for the same groups of products (e.g. like with the core box case explained above), so if you still have any separate sun drop options in your cart, we kindly ask you to change them for products with a sundrop version.
