A petition set up by a "devastated" shopper to try to save a John Lewis store has gathered more than 8,500 signatures in 24 hours.
Caroline Sampson, 57, said the shop was the "backbone" of Watford and is urging the town's council to ask the company to rethink its decision.
Mayor Peter Taylor said he would be "demanding answers" from the firm.
A spokesman for John Lewis said: "The proposed closure is not something we take lightly."
The company announced on Thursday it would be shutting eight stores around England, including Watford, putting 1,300 jobs at risk.
Ms Sampson, who said nearly everything in her home is from the store, said it was "desperately needed" in a town which had already lost BHS and Debenhams.
"There are a lot of very upset and very angry people who won't take this decision lying down, I don't think we should let it go without a fight," she said.
Former employee Ms Sampson, who worked for Waitrose in the 1990s, set up her petition within hours of the news being announced and said the response showed people's "affection and support for the store".
"I'm absolutely devastated by the news and I do wonder what is going to happen to Watford shopping centre... we have no department stores left.
"A friend phoned me yesterday in tears saying 'John Lewis is Watford'.
Ms Sampson, from Bushey, Hertfordshire, has also written to her local MP Culture Secretary Oliver Dowden about the proposed closure.
"I appreciate that many people shop online, but you can't beat feeling a fabric for yourself, trying something on, or having someone well equipped enough to describe the merits of a washing machine or a computer," she said.
Elected mayor, Peter Taylor, said he met with John Lewis on Thursday and together with the management of shopping centre Intu had tried to persuade the retailer to stay.
"I will be demanding answers to people's questions, particularly why they have chosen to close the Watford store, and whether there is anything we can do to reverse this decision," he said.
A spokesman for John Lewis said: "We are incredibly grateful for the support our Watford shop has received - the strength of feeling underlines what a difficult decision this has been."
