Using events throughout the year as a way of promoting your merchandise is a great way to boost sales on ebay. If you are retailing in the UK there is an 'event' associated with almost every month. You can easily integrate one or more of the events below, into your marketing plan, for example:-
January - January sales
February - Valentines day
March - Mothers Day
April - Good Friday/ Easter Monday (UK)
May - Get ready for Summer/ Make one up
June - Fathers Day
July - Back to School (kids)/ Make one up here, too
August - Back to School (kids)/ Make one up here, too
September - Get ready for winter
October - Summertime ends - turn clocks back
November - Halloween/ Guy Fawkes night
December - Christmas
If you add in sporting events and competitions, minority ethnic festivals and events celebrated locally you can easily promote your products all year round.
If you truly wish to skyrocket your sales be patient and remember that timing is everything.
