Antonio - Ok. When you see a new merchant product page on Rosity and you decide to look at that product you will almost certainly be clicking on the 'image' samples, of which there are normally three, to decide if this product is for you or not. If the product has been properly labeled it will tell you whether or not you need a required product for it. It's at this stage that might be given the product's name and thats all, you are expected to know what it is and where it is to be found. If there isn't a link to click on that will take you directly to that 'required' product page to buy that specific product then you give up on it. Simplying saying that this item requires such and such by such and such is not enough. You have to be very specific and helpful. Part of a website address or site name is not enough because when you get to the site, assuming you do, you are probably going to be looking for the product there too. Its frustrating and time consuming and is very unfair to the buyer to have to do this.
