Both free shipping and no free shipping on AliExpress have their advantages and disadvantages, and the specific choice should be made based on the actual situation.

The advantage of free shipping is that it can attract more consumers and simplify the purchase process, making it easier for consumers to place orders. Moreover, for consumers who buy small items or low-cost items, free shipping can also provide better cost-effectiveness.

However, free shipping also has some disadvantages. First, if sellers do not carefully consider logistics costs, it may lead to a decline in profit margins or losses. Second, free shipping may lead to abuse by some consumers, such as frequently placing orders for small quantities of goods, which may increase the seller's workload and logistics costs.

On the contrary, the advantage of not offering free shipping is that it can reduce the seller's costs and ensure stable profits. In addition, not offering free shipping can also encourage consumers to buy more goods at one time, thereby increasing the transaction amount and profit margin.

However, the disadvantage of not offering free shipping is that it may make some consumers feel that the price is too high or not cost-effective, thus affecting sales. Therefore, whether to choose free shipping or not requires comprehensive consideration of factors such as product features, target customer groups, market competition, etc. to find the most suitable strategy for yourself.
