My longest wait has been about 12 days, but from what I've been reading on the forum, quite a few artists have had to wait 2 weeks or more.   Be patient, keep creating and good luck with your store !

Just a tip...if you have cards that you want to be available immediately, use your "private gallery"...upload as usual, click, "pivate" "no review" and it is instantly available in your "Private Gallery".  
 
I often use this for requests and custom cards when I can send the  link.  Even better, upload the link to your blog (assuming you have one), send that link, and then you get an artist AND sellers fee...adds 50 cents per card to your earnings up to 25.00 per order.  For example, I had a customer who wanted a custom christmas card...I designed it, put it on my blog, sent the link, she ordered 75...I got the gcu artist commission plus the sellers fee (in this case 25.00).  Just a thought....I also notified the customer that I have available matching postage stamps on zazzle...they bought those too.
