Usually stuff from Nstuf comes quickly. I don't think I have ever had to wait longer than a week, usually much quicker. You can always get the overnight shipping if you're that impatient, but it realyl depends on where they ship it from. Sometimes they ship out from Kentucky and sometimes from Seattle and California. Just go to your account and look at track packages. It tells you where you stuff is located at the moment.
Okay, this will sound off-the-wall, but it works. I had a bad flea infection on my dogs a few years ago and they had sores and loosing some of they hair. None of the shampoos, sprays or oral treatments worked at all. The dogs were tearing at their skin.
Then a friend suggested I try bathing them in Murphy's Oil Soap. Yup - the wood cleaner you buy in grocery stores. She's read about it in an all-natural type magazine. I had nothing to lose - so I tried it. BINGO! Fleas gone and scratching stopped. Period. I did give a second bath a week later just to make sure, but I hadn't see a flea in the meantime.
