Why Do HSN Top Quality Designers Cheapify Their Goods???

Why do HSN top quality designers always end up either cheapifying their goods, or they disappear altogether (ala, Joan Boyce). The entire lure/attraction to Heidi’s jewelry line was the Swarovski crystals she used (well known in the industry to be the best). Her followers are Swarovski fans – those that have lots of Swarovski jewelry – so what does she do? – starts buying cheap crystals from China – goodbye quality line. Marlawynne – known for her superior line of fabrications & quality – what does she do? – starts using cotton & acrylic far cheaper fabrications – quality of goods – “going down” – why can’t these designers get what it is that put them on the map??? Joan Boyce – top fave designer – gone – what did HSN do wrong to lose her??? Either their few quality designers cheapify their goods – or they disappear – why can’t HSN & their designers get that some shoppers are actually shopping quality & cater to them as well as those that are merely shopping price?????
