As long as you paid the $10 for the month to receive the shirt, it wouldn’t be dishonest. Dishonest would be pledging but not giving and yet still getting a shirt. Kevin understands that some people may do what you propose, but it’s worth the risk if some of those people stay on for at least a second month. Plus if you want that shirt, you’re probably a fan of his work, so the giving on Patreon is extra. Not to mention he gives some pretty nice perks, so it is difficult for someone to pledge and not come back if they like those extras. I’m sure that Kevin makes money on the shirt even if you only give $10, so it’s not like he’s losing out if you just pledge for the shirt. Sporting the shirt gives him free advertising, so he comes out ahead either way.
I personally wouldn’t do it, because the hassle to pledge would intrinsically motivate me to maintain my pledge for multiple months, costing me more in the long run, so I would just wait and buy the shirt when it reaches the store. Again, that’s just me. I try to look at more than just financial cost when it comes to these matters.
