Thanks all so much for the replies! =) And for going into such detail. I think I'm now very clear on what I need to do.
Well then, I have opened a furniture shop and am buying from market. It's quite a business, because it's landed me in an area I haven't looked at yet, and there seems to be weakening demand already. At least in this case, there are quality bonuses produced by other players for me to exploit.
In fact, I'm beginning to see weakening in demand in Toys as well, now. You know how a product looks like this below (pcs....S/S/A/W)?
Tricycle: 20......6/20/6/20
Well, at the beginning, I swear I seemed to be selling 20 tricycles every season. :] Anyway, that's what it seemed like. Now I am selling a lot less in the weaker months. How do you correct this? By making only 13 per wu for that shop (average of the months)? Or by beginning to reduce your prices already? And how big should the reduction increments be? Drop 5% every time you sell too little, or go down by 1 or 2%? Do you try different prices in different shops and see which performs? I'm afraid I can't spend all day online.
Anyhow, I'm going back to my cafes now. Tricycles, anyone? Lot's to spare!
