Pavers England — price difference

Address:

Mumbai City, Maharashtra, 395007

Hi Team
Today Bought a pair of shoes from Pavers England company outlet at mumbai domestic airport attaching the bill copy a sale tag was attached with the shoes and I was told that the discount is 30% on it but after surfing on the website of Pavers England the same pair is on 50% discount need to know the reason for the same.
Don’t expect such from a company like Pavers.

Looking for a positive Reply.Thanks in Advance.
