Data, continued

So we analyzed:
     1.  Big jump in # of customers in 2010.  Why?  Guess:  My sister Billi organized a major postcard distribution blitz
     2.  Sun. sales high in 2008, low in 2009.  Why?  Guess:  The vendors bought most of the items in 2008 on Sunday.  Our tally indicated no customers on Sunday.  2009 was a bust.
     3.  Sales have almost doubled in 7 years.  Why?  Guesses:  More customers, people come prepared to spend money, or the economy has improved.
     4.  For several years our greeters also asked customers how they had heard about us and kept a tally of that information.  The answers were varied, but many responded with "postcard."

And we made some decisions:

     1.  Extended hours were not worth the few sales.  Most sales occur between 10 am and 4 pm.  No more Sundays; no more extended hours.
     2.  For our space, the number of vendors should be between 27 and 30.  Otherwise it starts looking messy.
     3.  Postcard delivery just before the bazaar to restaurants, hotels, etc. is vital, so we designate people to do that.  And we continue to distribute during the bazaar.
     4.  Continue all advertising - newspapers, signs, posters, postcards...definitely the postcards, so now we order 5 - 6,000.
