Don't know how relative this is to our members here, but if you get the Exchange Magazine (which I think it's sent out to military/retired military) there is a few MLP coupons in it (this issue was all toys it seems)
$3 off on My Little Pony Bridle Friends Pony (Assorted) (run date Oct. 19 - Nov. 21, 2012)
$4 off on My Little Pony Princess Cadance (run date Oct. 19 - Nov. 21, 2012)
$5 off on My Little Pony Princess Wedding Castle playset (run date Oct. 19 - Nov. 21, 2012)

$4 off on My Little Pony Friendship Express train set (run date Oct. 19 - Nov. 21, 2012)
Those seem to be the only ones as far as MLP and Again I don't know how many of our members can use this info
