First of all, I would like to wish every member and especially everyone at webmasterworld that's made this community a superb place for learning a VERY HAPPY NEW YEAR!
I know a lot of people have commented on traffic been down during the christmas period but i have seen sales go up by 18% for December even though i do not sale christmas related product. Has any one else experienced an increase in sales in December.
Depends on the market - I sold a lot more underwear and games in December, but a lot less holidays so I think you need to ask that question in relation to the market you are in. Obviously some things thrive at Christmas time and even though you say yours isn't, most will be affected in some way by Xmas I would think.
