Got an e-mail with a voucher for $10 off. No minimum spend is mentioned; however, it's valid in store only. I've put a random e-mail address in the screenshot, but you can Photoshop or MS Paint your own e-mail address in, if you prefer (7pt Arial). Possibly targeted, though looking at the barcode's URL, it's a generic code. I assume you'd need a 'Friends for Life' membership (free).
Terms and conditions from the e-mail:
Offer valid from Monday 19th December 2016 to Sunday 29th January 2017. Illustrations photos and packaging are only representation of the products advertised. Retail sales only. Not valid in conjunction with any other offer. Offer can only be redeemed once and only at your local Petbarn store. Not available on www.petbarn.com.au.
Edit: Bostos has confirmed that he has received the same e-mail with the same barcode, so the barcode is not single use.
"Possibly targeted"? Seriously? It's got your email address on the voucher!
Poor form to suggest photoshopping of vouchers. There's ozbargainers and then there's ozbargainers…
