I always receive them without problems, but I don't order like this.
I order three tins per shipment, I get about 38 USD with shipping, never more than 3 tins
With this you ensure a few things:
that your orders arrive or are not inspected by customs.
If an order is lost, you don't lose too much of your money.
If the Customs inspects it and puts you the duties and taxes, the amount will be small, that is to say, that they can put you about 20 USD of taxes in one of your shipments?..you pay it and that's it, it is not so much.
But an order of 400 USD if customs stops it, they will put you some tariffs for about 200 USD, calculating by high and roughly.
In Spain it is illegal for stores (tobacconists) to sell tobacco online, but it is not illegal to buy it and bring it from other countries, you just have to pay the taxes, if you stop it to Customs, if not, then you get it without them.
I'll give you another example, I bought a boat kit for a model in a store in the USA, I was stopped by customs, it cost about 300USD, I do not remember exactly, and they made me pay VAT + postal fees for tramitation, almost 104 euros.
It happens with everything, not only with tobacco. Customs is random, sometimes they pass the shipments and sometimes they stop and inspect them.
