Saw this last night in the drug store down the street from my apartment:

It might be a little difficult to discern, but here’s the deal: On the top shelf, individual refill packages of Dove body wash are priced at ¥298 each; on the bottom shelf, special two-package sets are available at a price of ¥598 each — ¥2 more than the cost of purchasing two individual packages(!).

Apparently, in Japan, there are instances where buying in bulk is actually more expensive than buying items individually.

Shop in Japan and watch your savings grow!
