not tubes yet, but
I buy from Aliexpress and Temu, including successful returns/full refunds.
you need to pay attention
1. pick ’local warehouse’, the item is already in your country so ship/return is local
2. keep eye on both cost and shipping cost
3. some items have minimum order of more than a single unit, if a great price, think about giving gifts if you need to buy 2 or 3 of an item.
