I love that little Fluttershy bag
So cute! G3 merch like that does not tend to me more than $5ish unfortunately.
The magazines I am not 100% on. While they are UK, they are a little bit of an acquired taste and not everyone is on the look out for them. If someone is looking for one specifically perhaps $8; but in general I would not think they will be any more than perhaps a $1 above retail right now.
