Bought my Samsung S21 FE new sealed box on amazon Canada for $490 a few weeks ago, and Costco now has it on clearance for ... $700. So I did really good!
Ended up taking a Fizz "plan", unlimited Canada+USA talk+text with 4 Gb for $27/mo. Data will stack up over two months, so it should stay at around 10 Gb if I don't use it much. Data good for US use too. You can change "plan" every month if you wish, and Fizz is the only carrier still offering travel packs (data only), so no need to get a tourist sim card when going to Europe.
