So? Promos, freebies, combos, discounts, cashbacks etc are under the purview of each opco/individual market. LG Poland clearly feel that to deliver their Q1 numbers and they need a good bump in sales, which they can deliver by giving freebies away. In the UK the margins are likely far smaller, or sales good enough that they don't need to beg you to buy their products. Why should LG UK give you a freebie for pre ordering? If you're pre ordering, you want the product more than they want your business. Quite why you feel entitled to a freebie is beyond me. You clearly feel aggrieved enough that the only way to settle this is to order directly from LG Poland.
If the individual market feel they want to entice you to part with your cash by offering an incentive deal, it's their choice. If a retailer wants to do the same, it's their choice. I doubt you were bleating this much when LG UK offered huge cashback deals on the C8 and E8, while the rest of Europe got "NOTHING"
You're making a fuss about nothing. Move on.
