Saving - Potting Soil & Other Outdoor Price Comparisons!

I am in the mode of getting my hands dirty in my yard.  Busy cleaning, preparing and soon to be planting!  Yipee!  The time has finally come!  With that said, I am always trying to save some money on this fun job as well.  I would love to hear how you save money on the purchase of your annual flowers?!  This is one I struggle with.  I love pots and pots and pots of flowers at my house, but the cost of the plants add up quickly.  Suggestions welcome!

I am doing a little price comparison on potting soil and other fun outdoor necessities for this time of year, so thought I woud share them all with you.  It was sort of an afterthought this week, so it is not a complete list, but will update as I go.  Let us know if you have other prices available as well!

Prices in Red were updated 5/29/11.  I am unsure of the end date of the other prices, so you may want to call ahead and verify first.
