Prices run from $40.00 to $295.00 across 30 listed products. Payment is by bank transfer, credit card, paypal, zelle, and venmo.
Worth knowing before you order: unfinished template site. The site still shows the placeholder copy its theme shipped with, such as Lorem ipsum text. A storefront left in that state was either abandoned or never properly opened, whatever the product pages claim.
