I bought my Jamieson Vitamin B100 Complex in the 90+30 Bonus bottle. It lasted me just about four months, now that my first bottle is nearly empty; I've been watching for deals. At $15.97 as the regular price for this product, it works out to be .13c per caplet. Highly worth it when you read about their amazing super power...
The really awesome super power that I learned about:
Taking the Jamieson B100 Complex will actually help repair and prevent chapped corners of the mouth, lips and hands. I take a lot of medication and some of them really dry me out. The corners of my mouth were cracked and so painful that I considered simply not taking my meds anymore. That's how much it hurt. Thankfully, my specialist suggested that I get these exact vitamins. I rushed out and got them and started taking them the same night. Within just three evenings, my lips were healed! Like I said, I've been using this bottle daily for about four months now - and my lips haven't cracked ever since!
Another great part about these caplets is I am able to take them with my night lunch and all of my bedtime meds. Other brands and multivitamin packs suggest to take a couple hours before or after others meds.. But, I take meds four times a day - so it's nearly impossible to follow through with that order.
The honest downside: The B100 Complex are a large caplet. The best way to swallow it down is with milk. Silver lining: If swallowing large caplets doesn't work for you - Jamieson did just release a new chewable form (which I intend to try, so stay tuned for that review).
Slightly embarrassing tip: Take your vitamin with food. If you don't, you will notice that your urine is a bright weird color. Not to worry though, it's totally normal. :)

I use the B 100 and it is really effective and I find Jamieson to be the cheaper in price, even if it costs a high price. I try to find it in sale. I use it since a long time and I can see the difference on my energy level and stress.
