Would you be happy if you ordered something from XYZ company, saw the on-line bill for (say) $100 including shipping, and then you discover when the invoice goes to your credit card company that the bill was actually $120, because of unstated "handling charges." Would you just shrug it off as "I should have known?" Or, the delivery guys shows up at your door with your $100 item, and won't give it to you until you pay an additional $20 delivery fee?My friend, the OP message and the ensuing discussion is/because/due to/from/ US POLITICS. You can NOT escape it!! If it had nothing with the glorious US politics, we wouldn't have this conversation. In fact, we never did until the coming of Anti-Christ, I mean MAGA!!!
Wouldn't you say, "Why did the seller not tell me about this?"
