Don't accept their first offer
Sent off an iPhone 13 with an estimated price of £185.
I sent the phone myself via DPD as wanted it insured, item arrived safe and within a few hours I received an email saying there were some imperfections such as:
Marked screen
500+ cycle battery count
Issues with speaker
What followed was an offer of £80, to which i selected decline. I was then sent another email stating a further offer will be sent or steps on how to return.
A few hours later and another offer, this time £100. Again, I refused and had the same email as previous. After a few hours I received a call from them directly to discuss my price and steps on how to proceed.
I stated I would not accept their offer of £100 and that unless they can improve it by a good margin then to return it.
After them trying to explain all the issues and saying the original price given is just a "guide" they went away and spoke to their warehouse.
After 5 minutes on hold they came back to say they had a "spare" battery from another phone to put in this one and that the original marks on screen were not as bad as thought but still needed attention so on that basis they can now offer £140.
I was selling this phone on behalf of someone else and they were happy with the £140 so it was accepted and the funds hit our bank account the same day.
Overall, I wouldn't say I was happy or not happy with the service but I would point out that offering £80 and then a few hours later £140 doesn't sit right with me and for that reason I wouldn't use again.
I would proceed with caution then using this company, although it seems that most companies in this industry use the same tactics and prey on the weak.
