I went to buy a vinyl pool repair kit but they are not accepting credit/debits cards now, so I had to go to an atm, went back 5 mns later and the store is closed there s people still inside tho and one guy inside saw me and didn t want to open the door and sell me the kit.
Never gonna buy anything there, I won t recommend this place to anyone either.
Unprofessional!
