Nick here from Shopify.
Can I ask if you are using Oberlo with AliExpress or AliExpress by itself?
AliExpress is separate to Shopify completely, so we wouldn't have any control over where that is exactly on AliExpress.com. I took a quick look and did see if you added a product category in the search:
and then sorted it by newest product first you would get the newest products for that type of product.
You can also purchase products from AliExpress through Oberlo Shopify's partner. You can find out more about Oberlo from here. If you have any other questions about Oberlo, don't hesitate to let me know.
Hope this helps.
All the best, Nick
In case you are dropshipping from AliExpress, do give a try to this app called AppMagica: AliExpress Review .It helped us with importing authentic reviews from AliExpress and made our new store look filled with buyers :). Certainly a great way to make people feel your store is authentic and has people buying and leaving good reviews on your products, which can help in driving sales.
