If you're a tourist from outside the EU, you could receive a tax refund on products purchased at Junction 32.
Please take the following courses of action:
You will see a Tax Refund sign whilst doing your shopping. When you do, ask the cashier for a Tax Refund Form.
When at the airport and leaving the EU, present your purchases, receipts and passport to the custom officials who will validate any refund.
You must then find the Tax Refund Office at the airport or send the documents given to you via the post. Your money will subsequently be refunded.
