@computel I'm not sure why you changed your tone initially. You sound like a teenager who's parents just said you can't goto the mall or something. We gave you valid reasons why your suggestion was not needed, though this was only from our points of view. I personally think having an API i can pull from or develop plugins with would be a feature at the top of my list.
But the point being just because we gave you reason why you wouldn't need this feature, this is called criticism and is the intended action to a request of this type: suggestion. Why do we need this, why we don't, how it would help, why it would bog down the system, ect. If you do not want this type of feedback you should more carefully word your suggestions in the future.
I will reiterate my point though for this posts sake. When you import a item into your store, you are making a decision on how this is going to go. As you stated you offer a free shipping program on your store and you stated that you *only* import items with free shipping. Now if you think about this in the long term vs how much money you can grab from the customer at once you will see why this is not smart. You can't honestly say say that a shipping fee of say $3.99 on an item costing $10 which you already markup to say $30 is not worth it. You assume that you should be able to roll that shipping fee into the formula pre-calculations. This would as
@Direct Webstore stated above in so many words, just hurt your bottom line, cost you customers, and hurt your business.
In general you should stop your though process about how much money you can make at one time and think how you can make your items stand out among the crowd. You should assume that if your selling drones (or whatever product you sell) with AliDS, then so are 150 other people, probably 700+ shopify+oberlo users, and god knows how many other random e-commerce sites. You should think more about how you can write a better description of this item, find the item for the same/better price (with your shipping factored in on your end not the customers), or just in general work on keeping your customers. Stop worrying about how rich you can get doing nothing, think about how you can start a relationship with your customer, how you can create a source of income from said customer. Send out some emails, offer a BOGO deal for them, keep them coming back again and again rather then just once.
If this post has upset you in any way this is not my intent, rather a small suggestion for you to take on and learn from.
