  Consumer repurchase  interest is a  process  in 
which people repurchase the goods and services they 
have  purchased.  Most  consumers  use  the 
marketplace as a means of  purchasing  the  goods or 
services  they  want.  The  increased  interest  in 
repurchasing  consumers  in  a  marketplace  will 
certainly  result  in  increased  income  from  the 
marketplace  itself.  Shopee,  which  is  one  of  the 
largest marketplaces in Indonesia, based on a report 
from  Setiyawati  (2021),  explained  that  Shopee's 
revenue  in  2021  is  predicted  to  reach  US$  4.5 
billion-US$  4.7  billion  or  around  Rp.  64.5  trillion-
Rp  67.  .3  trillion.  Meanwhile,  with  Tokopedia  in  7 
2018,  its  revenue  has  reached  Rp.  73  trillion.  This 
value is estimated to increase to IDR 222 trillion in 
2019, or equivalent to 1.5 percent of the Indonesian 
economy  (Pramudita,  2019).  Furthermore,  with 
Bukalapak  announcing  its  financial  performance  in 
the third quarter of 2021, it reached a revenue of Rp. 
1.34  trillion,  which  was triggered by the significant 
growth  of  the  revenue  of  Bukalapak's  partners.  If 
you look at  Bukalapak's financial report  in 2020 of 
Rp  948.4  billion,  it  can  be  seen  that  there  is  an 
increase  in  the  Bukalapak  marketplace  in  2021 
(Anestia, 2021). 
  One of the efforts made by the marketplace to 
maintain consumer repurchase interest can be made 
with  several  promotional  techniques  such  as 
Cashback  and  free  shipping.  Cashback  is  a 
promotional  strategy  by  giving  coins  and  discounts 
to buyers when making a purchase transaction. Free 
shipping  is  a  form  of  marketplace  promotion  to 
attract  consumers  to  make  online  shopping 
transactions in the  marketplace. Consumers will get 
Cashback  and  free  shipping  together  if  consumers 
claim  the  two  vouchers.  One  of  the  advantages 
offered by other marketplaces is that the marketplace 
provides  various  types  of  products.  from  various 
sellers  in  the  application  or  on  the  website.  In 
addition  to  having  a  variety  of  products,  the 
marketplace  always  strives  to  create  trust,  safety, 
and  consumer  comfort.  This  is  done  by  the 
marketplace  so  that  the  desires  and  expectations  of 
consumers  in  shopping  through  their  applications 
and websites can be maintained; in this context, it is 
hoped  that  it  can  lead  to  consumer  confidence  and 
satisfaction during shopping.  
  Wenas  (Syukro, 2016) said  that  of  the many 
cities  in  Indonesia,  there  are  five  cities  whose 
consumers are the most active in shopping. The five 
cities  are  Jakarta,  Surabaya,  Medan,  Bandung,  and 
Makassar.  Of  the  five  cities,  every  day,  there  must 
be an order transaction in the marketplace. Students 
are one of the market targets for the marketplace in 
the  city  of  Medan.  The  cause  of  the  marketplace 
favoring  students  as  its  market  share  is  because 
students are very concerned about lifestyle in terms 
of  clothing  and  beauty.  This  makes  students  often 
make  purchases,  especially  in  the  field  of  fashion 
and beauty products, for their daily activities, one of 
the  marketplace  markets  is  the  University  of 
Sumatra Utara (USU) campus.  ).  The  University of  
Sumatra Utara. It is the largest campus in North 
Sumatra  Province.  In  addition  to  its  large  campus, 
the  University  of  North  Sumatra  has  a  very  large 
number of  students  compared  to  other campuses in 
North  Sumatra.  In  2021  the  number  of  students 
registered  on  the  USU  campus  will  reach  50,414 
students. The presence of online shopping presents a 
variety  of  products,  discounted  prices,  ease  of 
payment,  and  other  advantages  offered  by  the 
marketplace,  which  students  can  use  to  shop.  The 
advantages  offered  by  various  stores  in  the 
marketplace  can  be  used  by  students  for  the 
shopping  process,  for  example,  saving  time  in 
choosing  items  because  they  can  be  accessed  via 
smartphones, students can maximize the promotions 
offered such  as  discounted prices  and free shipping 
to  save  their  pocket  money,  so  you  can  make 
purchases at a later date.
