prix pièces VOLVO en hausse ?

Bonjour,
Après avoir constaté une hausse de 10 livres sur un kit de joint de sail drive entre hier et aujourd'hui, le site marchant concerné m'informe qu'il suit la hausse initié parVolvo. Et que comme ils restent moins chers, cela leurs permet de suivre le wagon à la hausse:

Dear xxx,
Thank you for your email, I can offer you this product at yesterdays price.
Volvo have increased their prices across the whole range so our prices have followed but we are still cheaper than them on the diaphragm kits (Volvo Retail price is now £225.00 Plus Vat for this product).
I will amend your order and I will send you a secure payment link from our card processor, WorldPay for the total order amount and once this has been paid we can process your order for you.
I look forward to hearing from you soon.
Kind regards
"
