MIL needs blister treatment packs

I went out to the living hall and found that my mother-in-law has taken out all her shoes and were packing them into garbage bags. Those were fairly new shoes which she bought not too long ago. I asked her why is she throwing them away. She says she's not throwing them away, merely giving them away. She'll be sending them over to the orphanage near our house. She says she gets blisters whenever she wear those shoes. She needs some Blister Treatment for her feet now and asked me to go to the pharmacy to buy them for her later. Okay, no problem. I'll be going back to my mom's later.
