The least expensive box of Medifast is $15.50. At 5 meals per day its $11.07 per day.
Wonderslim is $9.99 per box. This comes out to $7.14 per day
This does not include any discounts. You have to be a Beslim member of Medifast for a few months before you can get the 12% discount.
Free shipping after $200 net
Wonderslim however, has free shipping over $79. You receive a 10% discount at $99 and 15% discount at $399. This is with no monthy commitment. As far as taste, I haven't tried yet, but it has good reviews.
The variety seems to be about the same. Medifast offers interchangable bars..up to 5 per day which Wonderslim doesn't offer.
I've decided to give Wonderslim a try. I don't mind saving money at all and be considered doing the poor mans version
