Tax Deduction for UK Residents Purchasing from Apple in the EU

Hello!

I am a UK resident interested in purchasing an Apple product from an EU country. I would like to understand the process regarding tax refunds or deductions.

1. Is there a difference in tax treatment if I purchase the product online from Apple’s EU store versus buying it in an Apple retail store in the EU?
2. As a UK resident, am I eligible for a VAT refund when shopping in-store, and does this also apply to online purchases?
3. Are there any specific steps I need to follow to claim a tax refund, such as providing proof of export or using specific refund services?

Any insights or experiences would be greatly appreciated!

Thanks in advance.
