Steph McGovern and Alex Jones are in north London to meet the Parmar family. Graphic designer Sachin and his wife Nisha have two sons, five-year-old Sai and two-year-old Druv. They love the finer things in life and when it comes to shopping, design is everything.

Nisha and Sachin love to entertain and have recently renovated their kitchen. But this design-conscious couple believe you have to pay to get the best quality and design. Can Alex and Steph convince them that they don't have to spend a fortune to get the look they're after?

To show the Parmars the reality of their overspending, Alex and Steph resort to shock tactics. They raid the family home and, armed with the evidence, they create a pop-up shop filled with the contents of the family home. Will this force them to face up to their spendthrift ways?

To really challenge them, Alex and Steph give their home a bit of a makeover, taking away their usual brands and repackaging them. Some will be cheaper, but to really put their product loyalty to the test, some items won't have been swapped at all. How will this design-focused couple cope with their debranded products?

From crockery to candles and kitchen gadgets to kitchen furniture, have Alex and Steph shown the design-obsessed Parmars an alternative way of shopping that could save them money in the future?

Professor Avi Shankar shows how brands use their packaging to catch our eye. Five travel mugs are put through their paces to see which one comes out on top, and Alex gets the Parmars to blind test three stand mixers to see if price really does equal quality.

The experiment is over, but have the Parmars embraced enough new products and changed their shopping and spending ways to save money? Show less
