I ordered two 15lb. bags from thatpetplace.com for a little over $50 shipped via ground. Took about a week and a half to get here from NY (i think it's NY, not at home right now). I only used one bag on my 20 gallon that I mixed with profile from home depot. I wanted the extra so I wouldn't have to order it again for the next tank (inevitable now... ).
They're not here yet. Do you happen to have the tracking #? Most shipping companies come by a little later in the evening so it could show up by the time you read this Robert.
