Parts pricing

I am seeing hockey stick price increases on parts. One well-known supplier out of the UK has increased some parts (458 engine air filter and drive belt) 50-55% since I bought these items only 5 months ago.

And, no, this is not tariff related. These prices are BEFORE tariffs and duties. UK parts are supposedly tariffed at 10% but I was recently hit with a 34% charge.

Perhaps we need a "best price for parts" thread.
