Online?? In store??? Pricing???

Between 11 and 14 april 2022 i have phone the builderswarehouse customer nr. They said they do not have a contaxt nr forthe bedwortpark builders warehouse store but they are gald and wiling to assit with any questions. I asked about if the store are selling a auger machine ( that drills into the ground) the customer person rep**** yes they do. He gave me the price of R2499 and the drill bots startingg from R118 depending on the drill size. I asked if they have stock at Bedwortpark on which he said yes there is 4 in store. On 2022-04-21 my parents went to buy the auger at buuilderswarehouse bedworthpark. In the store they were quick to assist. My dad asked about the auger and the sales person said yes they have. He even went and collect a trolley to put the auger in. Mu dad went with him and notice the price on the shelve. He asked the saleperson to just double check the. Price as there. Is a difference in the. Price i have phoned for. The sale assistance went and request the. Price and came back to my dad statinf the price as R5300. Ny dad said no thank you he is not taking the machine as the. Price difference as more than double. As my dad walked out anothe sale person also spoke to himand explain that there might be a difference in price on line than to price instore. My complain is not about service or product but about the huge price difference. Is this. Possible?... Needless to say my dad took the bussiness in buying the auger to another company. There is however thing that my dad saw. Inside builders which he needs but we are to scared to go back. What if the instore price on the items are again more than double the online. Or is is going to be switch so. That. Online. Is more than. Instore.?
