Customs Duty = Nil (because the value of the goods is less than £135).
VAT = 20% of £32 = £6.40 (payable because the value of the goods exceeds £15)
Customs examination fee = £8.00
Total to pay = £14.40.
You can't avoid the fees unless the package can be split into two. e.g. if you're buying 2 DVDs at £10 each then sending them separately would avoid the VAT (and the examination fee is then waived because there's no Duty or VAT to pay).
The foregoing assumes that the item you're purchasing actually attracts VAT. If, for example, it's a book, then there's no VAT and consequently no examination fee, so there would be nothing to pay.
