Home Depot - Burnaby

I was trying to get a paintable caulking to fill gap between tile and wall. I was only trying to fill a short length so I want to get the smallest possible. I asked one of the store associates and he showed me where to get the smallest one possible, turn out the smallest ones were still 300ml, but it was relatively cheap. I worried that I don't be using it all up and will rest the rest of the tube, so I asked if there was any smaller ones, store associates told me that was the smallest, but he wasn't being very patient with my question. AFter all, the location of the store and hours was very convenience.
