Emirates Post heads-up: Receiving a package now costs 10AED + VAT

So yesterday I went to the post office to collect 2 small packages from Aliexpress. Ended up paying 20+3 AED to receive them. When I asked, they informed me that all packages (even books!) are now charged 10AED + VAT each, apart from documents. I had to wait twice: first to claim the packages, second to pay for their fees and receive them. Thoughts?</p> <p>Edit: Private / rented PO Box.
