This article is part of TIME’s ongoing Consignment Week series exploring the business of buying and selling things online.
Consignment sites can be as profitable or as dangerous as the sellers.
The key is to know how to read and navigate the sites you visit, said Richard D. Scharf, a real estate broker who teaches online buying at Columbia University.
Consulting: A Guide for Online ShoppingA recent article in Business Insider revealed that many online shopping sites charge hefty commissions, which can be a barrier to the purchase of the items.
The site of choice for this type of shopping, Amazon, charges customers an average of $1,400 a month in commissions to shop through its site, according to a report from Bloomberg.
In addition, some websites charge higher fees to advertise through them, according a study by the National Advertising Division.
Online shopping companies such as Amazon and Ebay have been criticized for charging high fees to lure shoppers into their sites.
But while many retailers like Target and Wal-Mart charge hefty fees for their sites, Amazon and eBay charge no such fees, according the National Association of Online Retailers.
Consumers can also save money by shopping through online stores through their online brokerage account, which lets them shop from a variety of brands, including Target and Macy’s.
These accounts allow customers to set a price and the total amount they want to spend.
This gives consumers more flexibility to shop for specific goods and services, Scharf said.
Conservation: What You Need to KnowAbout conservation conservation and conservation efforts, said Tom Scharff, chief executive officer of conservation group the Conservation Action Network.
Conserve the planet for all people, regardless of their background, said Dr. John A. DeCesare, president of the Environmental Institute.
Conserving the Earth is an initiative started by the U.S. Department of Agriculture to conserve wildlife and the environment.
It is aimed at reducing the number of people and animals dying on the planet and increasing the number and diversity of species.
Consciously buying a conservation item may not be the best way to protect the planet, Scharf said.
But buying a sustainable item can help people to think about how their buying decisions are making a difference.
Scharf, who has been an online buyer since 2005, said that the best part about purchasing conservation items is that it helps consumers see a greater impact in their buying choices.
Consumables: How Much Should You Spend for Food?
A recent study by National Geographic found that Americans spend an average $11.42 on grocery purchases each year.
That is about 2 percent of the price of the typical American diet, according data from the National Center for Health Statistics.
Consumers should also consider buying food that is locally produced, as many fruits and vegetables are imported from other countries, according Dr. Jennifer Hurd, director of the food and nutrition program at the University of Michigan Health System.
Consumption of fruit and vegetables is increasing in popularity.
According to a recent survey by the Pew Research Center, more than 60 percent of Americans now say they buy fruit and vegetable products from locally produced food and beverages.
Consume a variety: The Best Foods to Eat for a Sustainable DietA new study published in the journal Nutrition found that one of the healthiest foods to eat is green vegetables, with one cup of broccoli, one cup red cabbage and one cup leafy greens per day.
The study also found that consuming green vegetables daily has been linked to reducing the risk of heart disease, obesity and type 2 diabetes.
Consuming fresh fruits and veggies has also been shown to be a healthier option, according Scharf.
The National Health and Nutrition Examination Survey found that people who ate more fruits and veg daily reported lower levels of diabetes and other diseases.
The best foods to choose are the ones that have a lower risk of chronic disease, including fruits and greens, Schgarf said, adding that he doesn’t think that eating fewer vegetables will have any health benefits for you.
