Can I buy something on Vinted today even though I won't be home for 9 days?

The seller has to post within 5 days and In Post only keeps it for 3 days!
Can you use others like Evri or are they more expensive?

Just message them and tell them you want to buy it, is it okay to delay posting until XYZ day.

The seller can request a shipping extension with your permission. Just ask them to do this

Could you post it to a different address such as a friend or relative who lives near by so that you can pick it up when you are back?

I think it's ok, it's 5 working days rather than 5 days so should be ok.
