Asda chief executive Andy Clarke told ITV News he was "pleased" taxation changes were revealed in today's Budget, but noted that they would not happen this year.
Mr Clarke said: "Changes in taxation that affect customers and business has a positive effect on the company, we're pleased to see some level of tax change - but it's not in this year. These are taxation changes that are going to happen in the future.
"That's good to see, directionally it's good, but for people who shop in our stores and families around Britain it's what they are going to see from tomorrow."
There were chaotic scenes in an Asda store in Colindale, north London today as shoppers fought to get their hands on discounted TVs in the "Black Friday' sale.
Customers scrambled and pushed to snatch cut-price deals as part of "Black Friday" in frenzied scenes seen across the UK.
A woman was reportedly taken to hospital with a suspected broken arm after a stampede at one shopping centre in west Belfast.
The traditional US event usually takes place on the Friday following Thanksgiving and marks the beginning of the Christmas shopping season.
Chief executive of mental health charity Mind Paul Farmer said that Asda will donate £25,000 to the organisation after selling a 'mental patient' fancy dress costume.
The official Twitter account of Mind wrote:
Asda have shown themselves to be extremely misguided with their ‘mental health patient’ fancy dress costume.
It is staggeringly offensive to the one in four of us affected by mental health problems and our families and friends, and troubling that some businesses are still so out of touch with the public mood.
However it is encouraging to see the groundswell of outcry on Twitter and that our voices are being heard.
We hope this will urge Asda as well as other retailers and manufacturers to review their processes and consider taste and decency on mental health grounds, to avoid fuelling stigma and discrimination that are so damaging for large numbers of the population.
A Tesco spokesperson told ITV News they have removed a fancy dress costume called "Psycho Ward" from their website and apologised "for any offence caused".
A spokesperson said: "We're really sorry for any offence this has caused and we are removing this product from sale.”
Asda has been criticised by charities for its 'mental patient' fancy dress costume but they are not the only major retailer selling outfits based on mental health issues.
Tesco sells a bright orange adult costume called "Psycho Ward" which has the word "committed" printed on the back.
The website's description of the costume says: "Dress up as the most thrilling psycho killer character of all time in this Psycho Ward costume, consisting of a bright orange, long-sleeved boiler suit with zip fastener to front 'Psycho Ward' printed on the chest.
"The same words (are) printed on the back in larger letters with a prominent 'Committed' stamp just below."
ITV News has asked Tesco for a comment but they have not yet responded.
A campaigner for the mental health charity Mind told BBC Radio 4's Today programme that Asda "crossed the line" after selling a 'mental patient' fancy dress costume.
Nine out of 10 people using mental health services in patient care report stigma and discrimination from a range of sources.
Stigma and discrimination is unfortunately still really damaging in England today and this kind of myth of the dangerousness posed by people, that you should be scared of anyone who has used mental health services, is really damaging.
(Asda) certainly crossed the line here and I hear it might well have been changed with the addition of mental patient, so it was definitely being used to tap into negative stereotypes.
Mental health charity Time to Change said Asda's fancy dress costume "reinforces the myth that those with mental illness are all violent" and they hoped the outcry would lead to other retailers withdrawing the outfit.

Asda is recalling packs of its own-brand Curried Chicken Snack Pack after traces of Listeria were found.
As soon as our supplier informed us of the positive test result we removed the snack pot from our shelves. While this is a serious issue, it affects a single batch of less than 500 snack packs.
