Friendly advice: if people are talking throughout the chapter or "scene," if you will. Use quotation marks or narrate it through.
Examples
"I don't think you should buy that," -random name here- informed me with rather too much excitement.
Narrating it through would be something like.
She droned on and on about what I could and couldn't buy.
Not hating, just constructive critisism and trying to help you out.
Sorry if it came across as mean.
