environmental requirements are very high. However, because he just bought a house, followed by decoration, which made him shy for a while, the expensive real paint far away, it was on the advice of a friend to buy a brand of preferential promotion of sample paint.
small editor through visits to a number of stores found that the sale of sample paint brand is not in the minority, many merchants also to upgrade the goods, shop decoration and other reasons for the sample paint promotion, preferential discount between 50% - 7 fold, really very attractive.
merchants in the sale of sample paint will often be in the contract marked "sample promotion, no return" the words. Is it legal to do so? According to the paint merchants, the warranty terms and age of the sample paint are the same as the new product, but can not be returned for exchange.
explained: because the price of the sample paint itself is very low, and most only one, so can not be exchanged, otherwise the manufacturer will have to re-adjust the production line. When it comes to returns, merchants say that because they are sample coatings, they are not returned once they have been sold.
most merchants in the sale of sample paint are playing "low-cost" "environmental protection" and other propaganda, which is why it attracts consumer attention.
