Ex7BD: May want to check this one, as it did increase temporarily to 1.99€ (it was 0.99€) and regular price is still 4.99€.
Cavalary: Probably a regional pricing glitch? Seems "fixed" now...
Could be, usually i check gogdb that presents the info in $, that indeed its not always 1:1 (as one would expect for obvious reason), but in this instance its comparing $ v $ hence my comment.
Not an expert on the why, just sharing what looked like a mistach in comparable numbers :)
