When you consider you can get the s20 plus for about £30 more doesn't sound that good a deal imo.
same here got form ebay for £320 a grade was like new would not buy this as new 5g phones are coming out plus s20 will go down in price too

This price has gone up, it was £520 for months.
How do you know? Even for a like for like comparison with new, this is a bad deal. Search on HUKD to see the S20 deals that were posted lately.
