Xi' an children photo photography group purchase

I bought a copy on a cheap group-buying website before, so I'd like to give some advice: generally, if you buy a personal photo on a group-buying website, you should first look at whether there is hidden consumption in the content, and the price of the group-buying will be lower than the market price, so you won't be asked to pay for it, but some group-buying will initiate the purchase online and pay a small part, and you will pay the rest at the store. It should be noted that when taking photos, the makeup artist should ask if there are any charges for the things you use, such as false eyelashes, essence, facial massage, free for public and private.
