She obviously routinely buys a lot of knock offs, hence why she purposefully doesn't include them in hauls so she isn't highlighting the fact or having to say what she paid for those - like those hats that made it into a 'favourites' video but not into the NY haul or the really high end bags and jewellery. The only stuff she's happy to give a price for are the mid range things she actually 'trets' herself to every other day - NB trainers, White company candles, Zara clothes left right and centre, half price Coach bag for a few hundred pounds, that sort of thing. I think that is a much truer reflection of where her finances and disposable income sit. Perhaps she is trying to keep up with Anastasia.
Still those things aren't feasible for an awful lot of people so I've no idea why she feels the need to make out she is better off than she is when a couple of years ago she was crying her eyes out in relief that her daughter had bought her a working fridge. The amount she spends on mid range brands she could probably easily save for a higher end piece- I expect she was hoping Ana would treat her in New York or will suprise her with a Chanel bag later on in the year. Sad life as an adult woman, really.
