Key Delta Pinetown charges over R150 more for the same part, comparing with other GM branches.

Can someone please explain why Key Delta in Pinetown charges R150 more for the exactly same part, I bought from Bates GM in Shelley Beach?. I recommend you check prices, before you purchase any items from Key Delta Pinetown. Also please make double sure you get the correct item. Due to their refund policies you may be frustrated with the credit refund.
