There are some things where two can be reasoned into logical. But then there are others where it seems to make little sense.
Two when they are cheap and two of them totals $15, perhaps $20.
But 2 x $20 would appear to greatly limit the number of interested parties.
Conclusion: either meh doesn’t have very many of these so even at the double price, they hope they’ll sell out… or Meh has a shitload of these and is desperate to unload them, even to the exclusion of price-quantity-packaging sanity.
