But you're using a knife daily, so I presume you know what is dangerous about a knife, (not how to make one!), or say you use a credit card. Should you not have at least a vague idea of the concept before you use it responsibly? That's all am asking for.
You presumably rely on brands, yes? Same with the URL, make sure it is in fact the 'brand' you're looking for. Am not saying it's 100% foolproof as buying counterfeits isn't hard either. But at least do the bare minimum to check.
To make sure I'm not accidentally buying H0me D3p0t brand nomex.
