There’s no perfect answer! The good news is there are tons of options, so you can find a price to suit your budget. If you want to sell online for $20 or less, check out our Best Ecommerce Platforms Review, which includes website builders like Wix and Weebly.
For dedicated hosted ecommerce solutions, Shopify starts from $29 a month, and BigCommerce starts from $29.95 a month. Self-hosted solutions are a lot harder to calculate because hosting plans vary so much.
You can get hosting for as low as $2.95 a month from Bluehost, up to as much as $119.99 a month on a different Bluehost plan. It really depends on the size and needs of your store. Remember to include the cost of add-ons in your budget too.
