Where is the Spinach in Providence?

I've checked both Whole Foods and Eastside Market, and none of them have whole heads of spinach!! They have bins or bags of baby spinach, but no whole bunches. What is going on? Is there a spinach shortage? My favorite salad is shredded whole spinach with a little bit of parm and vinaigrette, and I haven't had one in nearly a month - usually I eat three or four of these a week. The horror! I have one last hope: the Stop 'N Shop in Rumford on the way to work. Keep your fingers crossed!
