I'm very late to opening my pool this year due to new construction of a pool house being behind schedule, but we're about to get it going. I was wondering if anyone had experience finding good deals on pool chemicals through amazon prime. I have a SWG but I think someone has broken it during the relocation of equipment. It won't power on at all so I need to tinker with it a bit to see what happened. I'm hoping they just installed the new keypad incorrectly. I can't bear the thought of going through a season without it, but if I'm going to be stuck buying chemicals for the next 2-3 months, I want to get the best deal. I'm in a semi-rural area with limited resources. I have a Wal-Mart, Rural King, and an overpriced pool store nearby.
