Jacobs went into administration on 1 June and announced the closure of all its 19 shops a few weeks later.
The former chain’s business affairs have since been handled by administrator, PKF.
The Jacobs website still allows customers to register for online purchases, which involves supplying a personal email and home address, before choosing the kit they want to buy and requesting the type of delivery they prefer.
Amateur Photographer (AP) has found that it is only at stage four of the five-stage ordering process that customers hit a problem, with no option available for payment.
However, the web page does not inform customers that orders can no longer be placed.
A message appears on screen stating that a full refund will be made ‘in the event that an order placed during the administration trading period cannot be fulfilled’.
A spokesman for Jacobs’ administrator, PKF, told AP: ‘The website remains live so that customers can email their queries (which are being handled by the remaining staff) but products can’t be purchased online any longer.
‘Our agents are currently organising an online auction of remaining stock.’
He confirmed that administrators will shut down access to the Jacobs website shortly, ‘as part of closure of the overall business’.
A date for the online auction is yet to be set.
The last Jacobs branch to close was the store at London Road, Leicester which shut down on 21 July.
It had remained open, temporarily, to deal with stock clearance.
