BOGO on OshKosh B'Gosh pajamas, PLUS 25% off orders of $40 or more, PLUS 4% cash back

OshKosh B'Gosh is having a great buy-one-get-one-free sale on their pajama sets.  Most of their boy/girl pajama sets cost between $30-$32, and their baby pajamas cost about $24-26.  Shipping is a flat $6.  If you buy four sets instead of two, your total will be greater than $40, and you can use promo code STUDYGROUP to get 25% off your total.  AND, ShopAtHome.com is offering 4% back from your Osh Kosh B'Gosh purchases, lowering your costs even further.

Let's take a hypothetical shopping scenario and see how you can get four pairs of OshKosh B'Gosh pajamas for only $40.32 shipped, or $10.08 per pair:

1. Click through the ShopAtHome.com link to OshKosh B'Gosh to make sure you get your 4% cash back. (Remember, you must be a member of ShopAtHome.com and signed into your account to get your cash back.

2. Add four pairs of baby's or children's pajamas to your cart.  Let's assume, for argument's sake, that you buy four pairs of $24 baby's pajamas.  Your initial total will be $24 * 4 or $96.  Since OshKosh is running an automatic BOGO on pajamas, your actual total will be $48. 
3. Since your total is above $40, apply coupon code STUDYGROUP, which gives you 25% off.  This drops your price by $12 to $36.  (If you prefer to buy only two pairs, you will not be able to use this promo code, but you'll still get a great BOGO and cash back deal.)
4. Shipping is a flat rate of $6.
5. Your total on the OshKosh B'Gosh site, excluding tax, will be $42.
6. With your 4% cash back from ShopAtHome.com, your grand total for these four pairs of pjs (excluding tax) will be $40.32 shipped, or just $10.08 per pair of pajamas.
