Week 25 Summary 

 

We saw another setback in Week 25 on the back of some marginal improvements in Week 24. Lot acceptance from Electrical Testing dipped to 65% from Week 24's nearly 77% while lot acceptance from Physical Inspection sunk below 53% in Week 25 from 70.3% in Week 24. 

 

Results for the July poll are now showing 83% of respondents believe heightened buyer scrutiny is having a negatively impacting their sales.

 

Cast your vote, "Has the increase in buyer caution had a negative impact on sales and the market overall?".
