These are products I've used, mentioned or reviewed on An American Housewife are available quickly and easily (and affordable) from Amazon. Also note a great selection of low carb cookbooks. I can only get a few basic products locally so I order about 80% of my products online through various sources. I use a variety of sites and stores and I'm not 'married' to any one of them as I always make sure to check prices, shipping rates, etc. and make sure I'm getting my money worth. Low carb and sugar free products are not cheap so make sure you shop around to be happy with your purchase.
I also want to note that FINALLY Atkins has a really good, clear and concise printable pdf of exactly what you can have on Induction as well as the lists for the next 3 phases. The one I have in my binder is the same one I ran off back in 2002. After 2003 it was very difficult to find a good copy (the Atkins website and their program went through a lot of changes over the past 10 years) - but now there is. They are free to print and you can find them here;
