Based on demand/interest I'll set up a discount code for HN, let me know what products seem the most interesting.
It would also be great if the customization (putting a logo or QR code on them) could be done online.
I realise it's not clear enough that these are outdoor-proof (i.e. PVC), will change that on the store.
We do customise tags right now for folks and putting logos and QR codes on them is our number 1 feature request - so we'll automate this process on the store in the next 2 weeks or so. Thanks for feedback!
