3 risks come to mind:
1. weaker pound means it costs more to import
2. tariffs may change meaning imported stuff is subject to more/less tax
3. ports may be clogged up, meaning stuff struggles to get here, meaning lower supply, which results in higher prices
however....
4. prices rise over time, so simply by waiting you're guaranteeing stuff will cost more
5. it's black friday soon, could be some deals
6. changing your behaviour based on project fear is what turns worries into real impacts
so basically...
stop worrying about it + do whatever you were gonna do.
