To wholesale or not to wholesale

Picked up an order of my greeting cards at the printer today to replenish my dwindling supplies. I order my cards in small batches when I am running low on a particular style and I am almost out of 4 different Petal People lines. I am starting to save my pennies up so I can make a very large print run of all 11 of my card lines at once. I have had a few stores contact me about wholesale orders but I just can't wholesale when I print in small batches. If I spend a few thousand dollars, I can make a print run that is big enough so that my cards will cost only cents each. Now where did I put that lottery ticket?!
