Slower months are normally in the summer June-September and after that sales start picking up again with November, December and January being the best months. Some do see a decline of sales starting the end of February through to the end of March.

Around thanksgiving and around christmas and the new year sales are doing well, everyone spending their gift money, end of year bonus and so.

Sales.... that depends on the store. At CP you can have a sale and it can be a month long, but after that you have to wait 5 days to start a new sale. You cannot sell an item for less then $1.99 at CP. At RDNA sales are pretty much controlled by the store owners, I'd say the same of DAZ, but I'm not sure. RDNA gives you a good initial sale period, after that it's hard to get your items on sale, except for their once a year sales. DAZ has many more sales during the year. At Rendo you can set your own sales any time you like, you could run back to back sales (but you may be contacted about that by the staff, not sure never tried it). You can set it to a certain percentage off (it's not too much) and you cannot sell below a certain price. Rendo does run various special sales with a higher sale percentage, but your items need to meet the conditions. So far, after all these years my items have met these conditions 3-4 times, the rest has either been denied or I knew beforehand I didn't meet the conditions.

As for renders reflecting sales..... I've been a vendor for many years now and so far, during all these years, I've seen about 20 renders with my stuff in it, not many more for sure. Last month I sold about 50 items and around 50 freebies were downloaded. I've sold thousands of items with content, but only seen about 20 renders with my content so far.

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
