Since this year is nearly over (and I guess I won't spend much more money on commissions) I just had a look over all the things I ordered during the course of the past 12 month - holy sh...
This year, I have spent 1.598,98€ on 34 (25 / 988,14€ on deviantArt, 9 / 610,84€ on FurAffinity) Commissions from 21 different Artists. This does not include several sketch or "pay what you want" stream-commissions. It also does not include the ~5-10% Tip I usually give.
The turnaround time from payment done to final/finished art received varies from 0 to 183 days with an average of 23 days (this statistic does not include unfinished pieces, since there I don't have the time yet)
The most expensive Commission had cost me 150,90€, followed by one for 115€. The cheapest was for 5€, followed by 8€. This means I have spent an average of 48,45€ on each commission (I usually prefer full body, full color commissions - so that might explain the prices).
I am currently waiting for 8 of these commissions to be finished, and the one I am waiting the longest for was paid at Sep, 9th.
I honestly didn't think I had spent that much on art... but well I am not sorry about it. All commissions I received were really great pieces of art and I love every one of them.
If you want to take a look at my commissions (at least those uploaded to deviantArt) you can do so in the "Commissions" section in my favorites.
Here are some examples:
