   2.                                                   We note your disclosure
that "[o]ur shipping vendors have informed us that they will be

         shipping as a result of COVID-19 travel restrictions and other
impacts. We expect to delay
         our shipping times in order to minimize the impact of such surcharges
on our business, but
         such surcharges or the delays in shipping could harm our business."
Please amend your
         disclosure to quantify the impact of any surcharges or delays in
shipping that occurred
         over the holidays, if material.

3.       We note your response to comment 5. To provide context for investors
regarding the
         importance of the agreement to your operations, please amend your
filing to disclose that
         transitioning the cloud infrastructure currently hosted by AWS to
alternative providers
         could potentially be disruptive, and you may incur significant costs
for a short period, as
         you assert in your response.

4.       Please provide a GAAP calculated margin in the bullets listed in the
Overview on page 73
         pursuant to Item 10(e)(1)(i)(A) of Regulation S-K.
Our Business Model, page 75

5.       We note that you track order economics using contribution profit which
is defined as
         gross profit less distribution center operating expenses associated
with inbound item
         processing, less payment processing. This measure appears to be a
Non-GAAP measure
         that should be reconciled to Gross Profit pursuant to Item
10(e)(1)(i)(B) of Regulation S-
         K.
Compelling Cohort Behavior and Expansion, page 78

6.       We note your response to comment 12. It does not appear that the 2015
cohort is
         comparable to the other cohorts in your presentation because the 2015
and prior cohort
         includes buyers who made their initial purchase in one of at least
five years, while the
         other cohorts include buyers who made their initial purchase in one
year. Therefore, the
         growth in gross profit for the 2015 cohort appears to include at least
six years of growth
         for some buyers by the time they enter year 2016 presented in your
chart, while the
         remaining cohorts include only one year of growth by the fiscal year
following the initial
         purchase year. Please amend your filing to disaggregate the 2015 and
prior cohort data.
         Consider providing this information in a footnote or separate table to
preserve your
         desired visual presentation of the development in gross profit for
each cohort.

         including that you expect the automation of the remaining distribution
facilities "over
         time." To provide context for investors regarding your plans and the
time it will take for
         you to realize the benefits of automating your facilities, please
disclose an estimated
         timeframe by which you expect to replace your legacy non-automated and
lesser-
         automated facilities with new automated facilities, or tell us why you
are unable to do so.
         Further, please tell us why you determined not to disclose current
labor, processing, and
         distribution costs and expenses for your Arizona and Pennsylvania
facilities compared to
         your other distribution facilities to provide context for your
assertion that achieving the
         same level of the automation at your Arizona and Pennsylvania
facilities in your full
         platform would result in favorable economies of scale.

8.       We note your response to comment 15, and your amended disclosure on
page 82 that
         "[w]hen ordering a Clean Out Kit, a seller may opt-in to our Return
Assurance service in
         order to have any unaccepted items returned to them for a flat fee.
Otherwise, we sell the
         remainder of all unaccepted items to select aftermarket partners, such
as thrift stores and
         textile recyclers, for reuse and recycling." Please disclose the flat
fee, and the percentage
         of your revenue attributable to sales of items to thrift stores and
textile recyclers, if
         material.

9.       We note your response to prior comment 17. Please revise to present
the most directly
         comparable GAAP measures [net income (loss) and net profit margin] in
the table
         provided on page 86 when presenting Adjusted EBITDA and Adjusted
EBITDA Margin.
         Refer to Item 10(e)(1)(i)(A) of Regulation S-K. Additionally, please
revise the title of the
         discussion beginning on page 87 currently titled "Adjusted EBITDA and
Adjusted
         EBITDA Margin" to include "Net income (loss) and Net profit margin."

partnerships are an
         important component of your offerings and your mission. Therefore,
please briefly
         describe the material terms of your agreements with your RaaS
partners.
