italy blossom - there are 2 versions the light blue one and the purple one (and the magenta one but i think you mean one of the more regular ones).
the light blue version is slightly more expensive for my opinion.
if near mint i would say about 8 US$ for purple and about 10-15 US$ for light blue.
by regular bow tie you mean the CP version? there are also more versions, magenta hair, red hair and regular pink hair. their prices are VERY different.
CP italy bow tie with regular pink hair would be about 15-20 US$, maybe more as she is not so common for my opinion. depends on who is searching for her
applejack shy pose would be about 6-8 US$, she is common.
