The online store I help run is doing over 100% better than last month. This small store is only 5 months old though. I don't think this has to do with just Christmas though. I'm trying to figure out how much is due to growth and how much is due to Christmas sales. I seem to remember someone telling me Christmas sales generate 25% more sales than usual.

I'm also trying to figure out what sales might be like in January and February. We sell general item from many different categories so seasons should not really affect us.

To make things simple, all things being equal, If an average month generates $100 in sales. Christmas might generate $125 in sales and January might generate $75 in sales? Add as many zeros as you want to those numbers.
