Taobao pre-sale agreement is a sales agreement of Taobao. The specific purchase method is: first pay the deposit according to the deposit ratio set by the seller, and then pay the balance according to the pre-sale time period set by the seller, and the seller will ship the goods.

2. Pre-sale for one week means paying the deposit first, paying the balance in 7 days, and the seller will ship the goods.

3. Remember, if you cannot pay the balance payment time set by the seller, the system will default to non-refundable deposits.

4. Pre-sale refers to sales before the product officially enters the market. For some designs and inventions, pre-sales can be used to understand whether the product has a market, especially for some products that can only be produced in batches. After reaching a certain amount through pre-sales, it can be put into production, which effectively avoids the risks of production. For products that are not successful in the pre-sale process, it means that the practicality and popularity of the product need to be studied and demonstrated. This is a good way to avoid waste caused by batch production and conduct market research.
