FAQ for Mercato Online Orders

Please visit our store (Siam Seafood, 12053 Nebel Street, Rockville, MD 20852) and provide your name and order number to receive your grocery bags. 

-Can I add items or make changes to an existing Mercato order? 

Yes, we are able to add items to your order up to 48 hours in advance. Please email with your name, order number, and desired item/quantity. You can also add items yourself by logging into your Mercato account, selecting account options, and clicking on orders.

-Who is packing and delivering my Mercato order?

Siam employees are packing your order in-store and Mercato uses multiple courier partners to deliver your order. Please note that Siam is not responsible for the driver or the delivery experience and any issues related to this should be reported to Mercato Customer Service at

-Help, I am having technical difficulties on the Mercato website!

We are sorry to hear that you are experiencing issues with your online order. Please call Mercato at 1-844-699-2776 or email to reach Mercato’s customer service team and they will be able to assist. Please note that Mercato is experiencing very high call volumes, resulting in unusually long wait times. Please try searching the help center for answers to general questions. If you do not receive a response after 48 hours, please email us at and we will try to assist you.

-Why am I missing items from my original order?

Due to limited availability and high demand, some items may become out of stock at the time of shopping even though they were “in stock” at the time of confirming your order. If the item is out of stock, we will find the best substitution with your approval or cancel the item and remove it from your final bill. We apologize for any inconvenience and appreciate your understanding during these difficult times.

-Can I receive a replacement or refund if I am not satisfied with the product(s)?

We’re sorry to hear that our product(s) did not meet your expectations. Mercato handles all replacements and refunds as they handle the credit card transactions so please contact Mercato at or 1-844-699-2776 for assistance.

If you have any further questions, requests, or feedback, please email us at and we would be happy to assist you.
