I saw a deal on Groupon for LG 55" 4k Smart TV (55UH600V). They are selling it for £599. It is a European model and on amazon UK site, it costs £783 and €799 on German amazon. The Groupon page doesn't mention any warranty. Would I be able to buy a 3 or 5 year warranty (including accidental damage) from a 3rd party locally? Will anyone cover this European model? Also, are there any disadvantages buying from Groupon? I would really appreciate if someone can give some suggestions.
