My advice is, scan the full section at the end of each 'aisle' for anyone you want to speak to, they're all trying to sell a product so all want to speak to you. I politely told them I already had whatever they were trying to sell (unless its cake - always try that lol) or if it IS something you're looking for, have questions ready to ask them so that you're not spending ages talking to someone when you're not really after what they're offering. Take cards from them all by all means but keep the ones you're interested in in a separate bag lol it's great chatting to the first few then you realise everyone wants to hit you with full sales pitches! Enjoy x
