We are being asked a variation of this several times a day now - "I am in the EU can I still order because of brexit"
The answer our dear valued EU colleagues and customers is - Yes you can order, no problem.
To be more specific:
There is no brexit problem (yet). The UK officially left EU 31st January but nothing will change at all until at earliest December 31st 2020. Until then there we are in what is called the "Transition Period" where the UK and EU continue to operate as usual. This is supposedly to allow the UK and EU time to negotiate the future of trade between themselves. Until the end of the transition period there is no change to anything.
After December 31st 2020
This is when things will change. If there is no trade deal or the UK does not stay in the customs union (very likely as there is just not enough time :( then it will be like now when we or anyone else in the EU sends to a non EU destination like Canada, New Zealand, USA, Australia, Russia, Chile, Thailand etc (we do that all the time with no problems)
Depending on import regulations in each country they pay some sort of import tax. Most have some limit in value under which they pay nothing, USA very generous at around $800, others not so much, Norway around £30 for example (amazing how many orders to Norway are declared under £30 ;)
In addition we do not charge VAT on non EU orders - so it works out equal or better than equal....In fact most of the time better for them as we mark the values low to reduce costs.
Brexit is a disaster in many ways for the UK but for now there is 100% no change at all and afterwards the impact on private customer sales will be minor, most likely in terms of slower delivery due to customs checks.
Please just buy as usual as it is literally business as usual for now.
