A bit of background first:
When I was little and played Shining Force 2 on my MD I wasn't a really keen strategist, so I ended up having the most fun at first by using the control enemies cheat and having them goof around instead of putting up a fight.
One of the things that I recall being possible (and arguably the funniest), was forcing the CPU troops into simply discarding their weapons, making their attack puny and negligible.
Later on I found that the weapons and items I forced them into discarding would pop up in the deals section of shops for me to buy (later when I grew up I figured out that the game probably considered the event as them dropping their gear on death, and thus it would show up in shops.
I also realized back then that whatever rare piece I sold at a shop could later be bought back, even if the price was salty. Thing is, in Shining Force 2 that isn't really needed as you have the caravan as a mobile storage/HQ.
So now on to my question: In Shining Force CD is it possible to sell rares to the shops to free up space and buy them back later? I ask mostly because of stat boosters that are taking up room and I'd rather use them post promotion.
