There is another event coming up at Bath and Body Works on Saturday 30th- it looks like this one is available in stores or online.  If you shop in store- the sale runs from 1pm-5pm, if you shop online it is available all day.
You can get a free Into the Wild lotion (full size product) and tote bag with purchase of any signature collection item.
The freebies have a $15.50 value and are a limit of 1 per person while supplies last.  I seem to recall great feedback from you guys the last time they offered the free bag but I believe this is a pretty popular event and some stores sold out early.
Last time people were able to use other coupons in addition to this offer to get a better deal.  It is certainly worth a shot- you can try using this free travel size item with purchase Bath and Body Works coupon as well.
