What's Wrong?

I think because I got a lot done last weekend, this weekend was bound to be the weekend of "oh, crap!" And it was. My plan was to finish the bathroom while my mom worked on baseboards. Well, everything was going smoothly, i was putting the taps and shower head in the bathroom. I was missing one of the adapters for one of the tub taps. So i moved on to putting up the shower curtain with no nail putty, the putty was expired. What about attaching the vanity drain to the P-trap? It's not lined up. OK, how about the mirror? Oh, the mirror was scratched. The only things that went up without incident was the two towel bars and the bathroom door. I went to Rona twice to return and exchange that day. As well as i went to totem and home depot to pick up a couple things that i didn't want to at Rona. I'm so sick of Rona. If you don't buy Rona products from Rona, then you are ok, but Rona seriously needs to at the workmanship and quality of their product lines. I've returned and exchanged many things because they were either broken or damaged coming out of the box. I mean i spend time looking at the boxes, making sure they haven't been open or the product hasn't been tampered with or was a previously returned item before i buy them. So these items that i bought and returned/exchanged, must have been new and damaged in the box. #fail on Rona's part.
