To the right, under the Contact section, you will now find a Sales Enquiries page.
I do sell items fairly often, mostly when people contact me via my blog to see if I would be interested in selling something. There are things I would never ever sell, but I guess everything has a price.
If you are wondering if I have x, y, or x for sale, just pop me a line on the contact form in the Sales Enquiries page.
[A bit of a grammar point here: In UK English, the difference between inquiry/inquire and enquiry/enquire is that enquiry is used for a general question, whereas inquiry is used for a formal investigation. In US English, inquiry and inquire is used for both. Language in general is moving away from such clear distinctions, but I still use the way I was taught when I trained as journalist]
