Here's a hypothetical situation:
Imagine you could have nice 1-inch counters for your favorite tabletop game, whatever it is. Those counters would be really useful and have a nice design that enhances the artstyle of your game. The counters might be used on the tabletop itself as status markers etc, or as things like inventory items, equipment tokens, skills etc. that you have lying around your side of the table next to your unit cards/list.
You could have two options.
First option:
The counters are available for free as a downloadable pdf file. You would have to print the sheet out and mount it on, say, 1.5mm thick heavy cardstock/mounting board and then cut each one out with a metal ruler and hobby knife, which is quite a PITA to say the least. So as I said, they are free and you can make as many as you wish, but you do have to make them yourself.
Second option:
The counters are available from a professional manufacturer, mounted on magnetic sheet or something similar, pre-cut and at a fair price. However, depending on where you live, those might be only available overseas so you would have to pay for postage to your country (large letter size or something like that). You might find out later that you need more counters than originally planned and you'd have to order another few sheets, or you plan ahead and buy some spares which you might end up never using.
Which one would you prefer?
