You said you were searching for one "fiable" (viable? feeble?) way, DNA is one way.

Just try it. If it works, there you go. If not, then make an appropriate post and I (and many others) would be happy to help from there. Different methods work better for different items. I've read wish uses bots for basically everything which makes it very easy. Pay with paypal as well, which will give you a second option to dispute the order if your first attempt fails.
