Answer:
There are several perks or troubles that Costco business faces.
Explanation:
The first of these perks is the intense competition from other large retailers like Walmart, Target, or Best Buy. While Costco does have a niche: it tends to sell higher quality poducts for a slightly higher price, the competition is nevertheless stiff because that niche does not apply for all product lines that are sold.
The second perk is also competition, from online retailers, especially Amazon, which is larger than any traditional retailer, but also from a myriad of smaller retailers that emerge constantly in the online market, since the internet provides very few barriers to entry for new competitors.
Finally, the third peak is consumer preferences, and that is because consumers are constantly changing their tastes and preferences, especially in developed countries like the U.S. This means that Costco has to constantly adapt to new product lines, and discard other lines.
